Not to disagree with your post personally, but to others as well on HR, etc.
I'm 5' 11", 183 lbs, did 3500 miles on bike last year, 2 tri's, good swimmer, good biking, P*** poor runner
FOR ME:
assuming a fairly flat course:
a 4 mph walk is BRISK (20+ minutes) I hold about a 110 HR
a 18 mph bike ride is BRISK(20+minutes) I hold about a 120 HR
FOR ME
a 6.2 run is moving, HR= 140 (steady 10+minutes after w/u)
a 20 mph bike ride, HR= 130 (steady, 10+ minutes after w/u)
25 mph bike moves me into HR of how I feel that particular day.
For Me - again once 'steady state is reached' (usually 10-15 minutes)
after 6.5 mph running I reach oxygen debt HR goes above 151, will hit 160 and then I stop & walk
after 25 mph bike I reach oxy debt - must slow down
I can only hold a 7.2 run for a minute or so
I can only hold a 30 mph bike for couple of minutes
On the other hand, a friend of mine, does Ironman's would agree 100% with your post.
Point: all of us are different. Know your body, I agree TIME IS THE BEST MEASUREMENT TOOL.
