We Share the Sun: The Incredible Journey of Kenya's Legendary Running Coach Patrick Sang and the Fastest Runners on Earth
Sarah Gearhart (Author)
An enlightening biography a
nd gripping sports narrative that takes us behind the scenes into the lives of some of the world’s most elite runners in Kenya and their coach, Patrick Sang.
"I highly recommend this book." —Meb Keflezighi
At a secluded training camp in Kaptagat, Kenya, a small town nearly 8,000 feet above sea level in the Great Rift Valley, three-dozen world-class runners, including Olympic champions, world record holders and the fastest marathoner of all-time, share simple dormitory-style rooms and endure grueling workouts six days a week.
These determined, devoted, and selfless runners are who they are because of a man named Patrick Sang. One of the greatest—and least-heralded coaches in the sport—Sang is described by his athletes as a “life coach.”
In We Share the Sun, Sarah Gearhart takes us inside this high-octane world of elites of which few are even aware of and even fewer have ever seen. We are immersed in Sang’s remarkable story, from his college days in the US to winning an Olympic medal in the steeplechase, and his journey to become a man who redefines what coaching means. There is no singular secret to athletic success, but, as readers will learn, Sang’s holistic philosophy is like no other approach in the world. It is rooted in developing athletes who can navigate the pressures of elite competition—and life itself.
In these pages, we explore Sang’s influence on his athletes — including his unique and longstanding relationship with marathon world record holder Eliud Kipchoge — as they prepared for the delayed Tokyo Olympics and other competitions. We witness the remarkable recovery of two-time New York City Marathon champion Geoffrey Kamworor after a freak accident as he strove to earn his first Olympic medal. And we follow one of the world’s most dominant mid-distance runners, Faith Kipyegon, as she attempted a historic repeat title in the 1,500 meters three years after the birth of her first child.
We Share the Sunbrings forth the remarkable lives and stories of East African runners, whose stories are seldom shared. Through Gearhart's vivid prose, we experience the richness that exists in Kenya as we come as close as we possibly can to running alongside a current and future generation of elites—and the man who molds them into champions.

1. 'Fan photos have quadrupled' - has Netflix's Tour de France Unchained made riders more popular?
The show's stars have seen their profiles boosted by the new documentary
There was a feeling, or rather a hope, that increased interest in cycling would follow Netflix’s new Tour de France: Unchained documentary series.
Experts call it The Netflix Effect. Ask any F1 fan, and they will tell you how their sport surged in popularity after the release of Drive to Survive in 2019. Today, in fact, half of F1 fans in the US credit the series for their introduction to the sport.
Could the same happen to cycling? A month has now passed since Unchained hit the streaming platform, and although we are yet to see a seismic shift, the show’s stars have noticed a profile boost.
“When I came here to the Tour, normally at the airport I take one or two, maximum three, pictures with fans,” Soudal-Quick Step’s Fabio Jakobsen tells Cycling Weekly. “This time, it was 15 to 20. It has almost tripled, quadrupled, I would say.”

2. Brooks Hyperion Review: This is Different… Right? Right??
ROBBE: Way back when I was a younger lad and a fresh face at Believe in the Run, Brooks released the Hyperion Tempo, a lightweight trainer with a supercritical midsole, meant for– you guessed it– tempo runs. It was the complement to the original Brooks Hyperion Elite, one of the worst shoes ever created, which quickly evolved into the Brooks Hyperion Elite 2, a perennially-okay race day shoe. Our review for that shoe came out three and a half years ago (to the day!) of writing this review. That was in the before-times of Covid, if you can believe it. That’s how long it’s been between versions of this shoe.
We enjoyed that shoe a lot. In fact, it was one of my favorite shoes of 2020. Simple, lightweight, and responsive. It was a pure running shoe. Obviously, a lot has changed since then. Pretty much every brand has increased stack heights across the board, foams have become bouncier and bouncier, plates are more prevalent than a bus bin at Waffle House. Obviously the Hyperion has changed as well, and more than just the name.

4. 5 Ways Reducing Inflammation Can Make You a Better Athlete:
Run faster, lift more, jump higher—no matter your movement of choice, reducing chronic inflammation can have a tremendous impact on your athletic ability.
Run faster, lift more, jump higher—no matter what your movement of choice is, there are always ways to improve. But one thing can get in the way every time: Chronic inflammation.
Some amount of inflammation and hard exercise go hand in hand. If you’ve ever felt sore the day or two after a workout (and who hasn’t?), that’s inflammation. The key is how much you experience it, and for how long.
“Inflammation is a product of the immune system, but it’s not inherently bad,” says functional medicine expert Will Cole, IFMCP, DNM, DC, author of The Inflammation Spectrum. “We need healthy balanced inflammation levels in the body. Inflammation helps fight off viruses. Assists in healing wounds. And it’s needed to defend the human body against infection. So, in balance, it’s very important.

5. Should you be heat training?
Athletes and coaches are always on the look out for ways to increase the Return on Investment (ROI) they get from the long hours they put in to training. They want an edge over competitors and improvement in the face of diminishing returns from their existing training methodologies. As a result, there’s been a lot of talk recently about heat training.
Heat acclimatisation - where you go and train in a genuinely hot environment - and heat acclimation - training in a simulated hot environment - have long been accepted as a proven way to improve subsequent performance in the heat. However it’s only relatively recently that people have started to look at heat training as a way to improve performance in temperate conditions too. That’s despite the fact that there’s research going back to 2010 that seems to demonstrate a clear link between heat stress training and improved exercise performance in cool conditions.
How does heat training work?
Heat training is very likely to boost performance in temperate conditions because, as you train in the heat, your body adapts, increasing blood volume by expanding the plasma (watery bit) of the blood to make it flow more easily to the skin and working muscles. This helps with heat dissipation and provides a larger reservoir of fluid to lose in sweat before cardiovascular performance is compromised. This is something that’s also closely linked to hydration status and body sodium levels as it happens and that probably rings a bell if you’ve been a reader for a while or have chatted to one of our Precision Fuel & Hydration team in the flesh.

6. Jitters and Java: Your Genes May Affect Your Response to Caffeine:
Your DNA has a say in your caffeine buzz, but it’s still not clear how genes affect gut sensitivity to caffeine.
For most people, ingesting small or moderate amounts of caffeine (say 2-6 mg per kg of body mass) improves physical performance and can also lessen mental fatigue, especially when someone is short on shut-eye. Some people seem to think that more is always better, including when it comes to caffeine use, but the truth is that crushing caffeine is often a recipe for problems. Still, there is wide variation in how people respond to caffeine. One person might be able to down lattes all day long with no ill effects, while another may be stricken with jitters and stomach distress with a single energy drink.
While there are undoubtedly several reasons behind this variability in the response to caffeine, genetics appear to be one of the key factors. This isn’t really a surprise, as people’s genes affect practically every behavior or physiological response they have, from their fondness for cruciferous vegetables to their preference for different types of humor. (Personally, I’m a broccoli lover who appreciates the cringe-type comedy of The Office.) If you can figure out a way to reliably measure a human trait or behavior, it’s basically guaranteed that there is going to be some amount of genetic contribution to that characteristic.

7. Is Overhydration More Dangerous than Dehydration?
Here's why you need to monitor your water intake.
Being human is all about balance. We strive to find an ever-elusive equilibrium between work and life. We go to yoga classes in hopes of improving our physical steadiness. We eat an assortment of fruits and vegetables, but we also munch on chips and dip. And, from a physiological standpoint, our blood cells need balance, too.
As athletes—especially ones who spend time outdoors during a heat wave—the ethos we usually hear is “hydrate, hydrate, hydrate.” However, a 2020 research article from Stanford University School of Medicine offers a different perspective. In the piece, the study’s lead author notes that overhydrating is actually more dangerous than being dehydrated.
How Much Water is Too Much?
One of the most important things to maintain balance in our blood cells is the sodium-to-water ratio, says Tamara Hew-Butler, associate professor of exercise and sport science at Wayne State University School of Medicine. When you’re dehydrated, you contain less water, causing your blood cells to shrink. However, when you drink some H2O, your cells recover quickly.

9. Exercise under heat stress: thermoregulation, hydration, performance implications, and mitigation strategies:
A rise in body core temperature and loss of body water via sweating are natural consequences of prolonged exercise in the heat. This review provides a comprehensive and integrative overview of how the human body responds to exercise under heat stress and the countermeasures that can be adopted to enhance aerobic performance under such environmental conditions. The fundamental concepts and physiological processes associated with thermoregulation and fluid balance are initially described, followed by a summary of methods to determine thermal strain and hydration status. An outline is provided on how exercise-heat stress disrupts these homeostatic processes, leading to hyperthermia, hypohydration, sodium disturbances, and in some cases exertional heat illness. The impact of heat stress on human performance is also examined, including the underlying physiological mechanisms that mediate the impairment of exercise performance. Similarly, the influence of hydration status on performance in the heat and how systemic and peripheral hemodynamic adjustments contribute to fatigue development is elucidated. This review also discusses strategies to mitigate the effects of hyperthermia and hypohydration on exercise performance in the heat by examining the benefits of heat acclimation, cooling strategies, and hyperhydration. Finally, contemporary controversies are summarized and future research directions are provided.

10. ‘Tracking your period should be your superpower’:
The latest Telegraph Women’s Sport Podcast focuses on how the menstrual cycle can impact athletes and the importance of more knowledge .
It was not until her second year of university that Bobby Clay learnt how to insert a tampon – via a YouTube video. “I was a 19-year-old woman. I felt pathetic,” she says now. Yet Clay had never had the need to learn before.
A former middle-distance runner who won the 1,500m at the Junior European Championships in 2015, Clay had been tipped to reach the very top in athletics, but her promising career ended before it had truly begun when she was diagnosed with osteoporosis aged 18. Years of under-eating and over-training also meant she had never had a period.
“I’d never had a period, so I’d never even needed to say the word,” Clay tells the latest episode of the Telegraph Women’s Sport Podcast. “Periods stopping in sport, unfortunately, was seen as the norm, but I just never started.”
Hormone replacement therapy later kick-started her body and she has since had natural periods – hence the tampon video – and now Clay wants her story to help other women. After all, rather than being seen as the norm in sport, missing periods should be seen as a concern.

11. Move over menstrual cycle: Ovulation monitoring is the new gold standard to monitor REDs in female athletes:
Am I eating enough to be healthy and perform at my best?
Researchers know now that assessing the adequacy of energy intake in athletes is not as straightforward as crunching the numbers for calories-in (the energy we consume through the food we eat) minus calories-out (the energy we use to function, from basic processes such as breathing and blood circulation to the complex processes we use to work or exercise). Be wary of what the latest calorie tracking app is promoting as one’s daily energy budget, as the cost of all the human body processes that are involved in energy consumption and expenditure is incredibly complex (Burke et coll., 2018).
What researchers, athletes, coaches and health practitioners are really after is an understanding of an athlete’s energy availability status. Energy availability (EA) refers to the amount of energy left over and available for your body’s functions after the energy expended for training is accounted for from the energy you consume from food (Loucks et coll., 2011). Inadequate energy availability, or low energy availability (LEA), arises when there simply is not enough energy (calories) consumed to support critical body functions as well as extra physical activity, such as training. If this goes on long enough, athletes can face serious health implications. Typically, physiological functions of the body get neglected and only receive the energy that is available after the needs of physical activity are taken care of. The prevalence of low energy availability is assumed to be high in female athletes, and if persistent may pose a significant health risk (Melin et coll., 2014).

12. From the Women’s World Cup to Wimbledon, a Victory Everyone Can Share:
Across sports, female athletes are fighting a battle over what they put on their bodies and how much of those bodies they display.
We are in the quarterfinals of that global sporting phenomenon known as the Women’s World Cup. There have been, as usual, shocks and surprises. There have been, less usual, record-breaking crowds.
What there hasn’t been, at least compared to any other WWC, is a lot of white shorts.
No white shorts as part of the England team uniform. No white shorts for New Zealand. No white shorts for Canada, France or Nigeria — all countries that wore white four years ago. No white shorts as part of the home kit for the United States for the first time since the WWC began in 1991.
“It’s period justice,” said Dr. Akilah Carter-Francique, the dean of the School of Education, Health and Human Services at Benedict College in Columbia, S.C., and the former president of the North American Society for the Sociology of Sport.

13. 3 signs you may be running too much:
Pay attention if you notice one of these signs–you may be overtraining.
Feeling sluggish and worn out, even after a great night’s sleep and some nutritious food? Overtraining may be the culprit, and while it can be challenging to pinpoint, there are a few red flags to look out for. Defined as a condition that can occur when a runner pushes their training beyond what their body can adequately recover from, overtraining can lead to a decline in performance and potential health issues.
While some fatigue is normal in a tough training block, over time the effects of training too hard add up and can lead to burnout or other running-related ailments. Here’s how to know whether you are overdoing it.
Performance plateau or decline
Performance decline is one of the most noticeable signs of overtraining. Take note if you suddenly have a tough time hitting paces that used to be easy for you, or if your performance plateaus or starts to decline despite consistent training efforts. Your body may be struggling to recover adequately if you’re getting slower even when you’re putting in more effort.

14. Fast Talk Femmes Podcast: Exploring Continuous Glucose Monitors with Dr. Jamie Whitfield and Dr. Dana Lis:
Dr. Jamie Whitfield and Dr. Dana Lis discuss the body's ability to regulate blood sugar and practical applications of continuous glucose monitors in elite sport.
Dr. Jamie Whitfield is an Australian-based exercise physiologist and postdoctoral research fellow with his Ph.D. in skeletal muscle metabolism and physiology. He is the co-author of a 2023 study, “The Use of Continuous Glucose Monitors in Sport: Possible Applications and Considerations,” and has recently been putting his research into practice with high-performance sports.
In this episode, we discuss with Dr. Whitfield the body’s remarkable ability to maintain glucose homeostasis, even in the face of starvation. We also take a deep dive into the dynamics and complexities of blood glucose and the relevance of continuous glucose monitors (CGMs) in a range of topics:
Why and how are athletes using CGMs? Do most athletes know how to interpret the massive amounts of data to inform fueling strategies?
Do CGMs help or hurt athlete fueling practices? What is the expert consensus on their value?
Are there potential applications for CGMs to improve athlete health and well-being?
Can CGMs help female athletes individualize their fueling strategies and training?
Should the UCI ban continuous glucose monitors from competition?
