"I lost my period 8 months ago. I’ve gained 9kg. I lost my drive": Chloé Dygert describes how RED-S took away her joy of cycling
Cycling
Chloé Dygert had all the tools to become a reference point for generations in women's timetrialing, but one crash ruined that ambition. Still, the American fought her way back, won another rainbow jersey, and underlined her status as one of women cycling's household names. However her career was far from linear with several setbacks causing the 29-year-old to spend way more time out of competition that she would've liked.
Most recently, the American broke last week that she's dealing with RED-S (Relative energy deficiency in sport), a condition which has been holding her back for close to a year, by her estimates.
In an Instagram story, Dygert describes the complications she has faced as a cause of RED-S:
"I lost my period 8 months ago. I’ve gained 9kg. I lost my drive, my excitement, and my desire for things I care about. I’ll go to lunch and come home needing to lie down. I’ll go for a walk and spend the rest of the day on the couch."
No time to recuperate
Dygert's been forced to take a break from racing and even training after her face-first crash at Paris-Roubaix Femmes, but has since resumed training at the end of May... however it lasted for just one session before the diagnosis struck back.
"On the first day I managed to ride my bike for an hour, I contracted coxsackievirus. There are days I can barely function from exhaustion, yet I’ll lie awake until four in the morning unable to sleep. I have dealt with fatigue in my career for years, always just assuming it’s from the constant comeback so I didn’t think this was any different."
Chloé Dygert is one of the best timetrialists of her generation
Still, Dygert would normally disregard the shoulder surgery as yet another stroke of poor luck, had it not been accompanied by changes in her personal life.
"That is until there were signs of my body physically shutting down. More than my usual bout of injuries. Signs of unexplainable issues that normally are controllable. Uncharacteristic behavior. All things I ignored because I thought if I just pushed through, I’d get through."
Energy deficit
The weight issues were ultimately what first alarmed Dygert that something's not right.
"Most people who know me know that I've always been a good eater. I've never had issues with food, which is why being diagnosed with RED-S came as such a surprise."
"I've never been someone who was 'sickly skinny' There were certainly times I lost weight while preparing for a specific event, but never to a point that felt unhealthy. My body fat has never dropped below 15%, and outside of my mom occasionally telling me l was getting too thin, nobody has ever expressed concern that I was underweight. When the diagnosis came, my coach was just as surprised as I was. Those who know me know I don't have a problem eating."
"When I look at my situation, I don't believe my body was under-fueled because I was restricting food. I believe it was under-fueled because it was living under constant stress and was never given a chance to fully recover."
So many missed signs
"Looking back, there were signs everywhere. I just didn't see them."
The realization ultimately came through the professional eyes one of the team doctors who noticed something off with Dygert this spring.
"It wasn't until my team doctor pulled me aside in the hotel before Roubaix and told me something wasn't right that I started paying attention. Later, conversations with team management echoed the same concern: I wasn't acting like myself. My energy, mindset, and personality had changed."
But ultimately, it was the crash in Roubaix that allowed thoughts to settle and helped Dygert understand the problem: "Then came another crash, more time off the bike, and finally the conversations that started unraveling what had really been happening."
For a rider as talented, it's an insane amount of terrible luck to be dealing with yet another massive setback derailing her career. In order to resolve this issue, it's likely we'll have to wait for Dygert's competitive return a while longer. But hopefully, once she does so, she'll come back stronger.
"In my own mind, I struggle to justify it as enough of a reason for the results I’ve lost, the opportunities I’ve missed, and the failures I feel. But for those who have seen it all had the same reaction: how could one person go through all of that and still keep going? 11 seasons and not one went uninterrupted."
"It’s a question I am asked constantly... The answer is simple: it’s the only way I know."

- It doesnt take a genius to understand that Pogi is 1 level above and Pogi is younger that Jonas, so Jonas will not win under ordinary circumstances. Pogi has to crack hard for Jonas to win. It doesn't matter whether you defend Jonas or not , facts remain facts. Jonas himself says his numbers are better than 2022/2023, so Jonas is more or less optimized and we are just see the stochastic variation due to other factors. I think he will retire along with Pedersen in WC denmarkabstractengineer13-11-2026
- They only raced each other during the 2026 Tour, but here's a few metrics to look at. Stage 3 (Granollers to Les Angles): Pogačar won the stage, finishing 2 seconds ahead of Vingegaard (2nd). Del Toro finished 24 seconds behind Stage 6 (Pau to Gavarnie-Gedre / Col du Tourmalet): Pogačar won solo, Vingegaard finished 2nd (losing 2:38), and Del Toro finished 3rd (at +2:57, finishing 19 seconds behind Vingegaard). Here, Jonas Vingegaard outclimbed Isaac del Toro by 19 seconds on the mountain stageawp13-11-2026
- your clinging to the past. Jonas was dropped by del toro many times last year and jonas never managed a climbing numers del toro did in dauphine last year -entire year. Trend is also evident theres no discussion your living in the past, its beent he same with jonas for many years now and only developing, meanwhile del toro is rising and developing greatly. This is all obvious stuff and im not even a del toro fan. No point discussing numbers or this i suspect you dont watch much now but rather think its 2022 still cause this aint hard.miguel13-11-2026
- We can go through metrics if you like, Del Toro, who I do admire and support, is not on the same level as Jonas just yet. You will see that in early 2027 if they have any crossover races. I do hope they both race the Giro. You are correct though, Jonas is getting older and will not be able to hand on much longer. I see 2027 as a good year for him. Obviously behind Tadej though.awp13-11-2026
- What wins? Are you LA operating under a pseudonym?mij13-11-2026
- My point is this - Tadej, Remco, Seixas are all the outliers. Many riders don’t hit their peak until 28. It’s way too early to write him off. And the pogi slo guy that hates him - he’s also immature. Ayuso needs time.mij13-11-2026
- Then you need to use ur eyes or head if you have cause del toro already dropped jonas two times and beat him in tdf stages already this year.. Del toro climbed(dauphine) better numbers than jonas did all year too. So ur feelings and wishful thinking doesnt amtter del toro himself has already surpassed jonas infact just facts. Its also very evident for anyone objective that Jonas is declining alot, its just the truth and super obvious.miguel13-11-2026
- None of those victories stand, so there's that,wrsty13-11-2026
- No surprise there; it is British Sycling, yes, with an S
Rafionain-Glas12-11-2026 - I like Del Toro but he's not on the level of Jonas, by a large margin.awp12-11-2026
