Endurance and Fatigue and RAAM

Endurance and Fatigue and RAAM

There have been a number of studies in the past few years that challenge the limits of one's body.
Is fatigue in the body or in the mind?

The recent insight is that one's mind sends fatigue signals to the body as a protective mechanism when in fact, you have reserves to keep going. But we all know that ignoring these signs could be dangerous.

This topic was covered in last week's NPR show Radiolab...........

http://www.radiolab.org/story/91710-limits-of-the-body/

The segment starts by talking with Julie Moss who had a bonk for the ages at one of the earliest Ironman races.
Her epic finish is credited with giving triathlons a huge boost in the early days. 
The triumph of the human spirit.
(I didn't know she had done this race on something of a lark).

If you have never seen the video of her collapse, it may be worth watching.........

The Radiolab program then covers some of the science of fatigue, and then explores RAAM, including 5 time RAAM winner Jure Robic who later lost his life on a training ride crash with a car.

Worth a listen.

Re: Endurance and Fatigue and RAAM

I used to ride with a woman when I lived in Virginia in the early '90s who was training for RAAM.  Part of the regimen clearly involved formal training through sleep deprivation, so clearly there is the need to learn to mentally push beyond the physical limitation of having only ~1-2 hours of sleep per day, for ~8 days, at best.  She was an amazing rider in terms of both capability and temperment who made it from Irvine, CA to Slapout, OK where she unfortunately got sidelined by a bad case of bleeding saddle sores.  Sometimes even defeating fatigue signals from the brain is not enough.....
