What's your heartrate?

The OLN commentators (Liggett esp) were talking about heartrates in the race. Apparently, LA's resting rate is 32 or 33 and he maxes out at 201 but works at 180-190. Wow.

The physiology of these racers is just mindboggling. I know that everyone has their limits, genetic gifts, etc., but still...

Makes me want to do more cardio to improve my VO2 max, etc.
