do you use your heartrate zones in race strategy?
I've done some reading (mostly Friel's books, total heart rate training , Mountain Bikers training bible) and taken a few suggestions and I'm going to formalize my training.
my question is now that I've calculated my LT and know my zones
I did a 30 min TT and my average of the last 20 was 172 so this is my LT as a point of reference
races here are over pretty tech single track and guys who win are doing 24-25km (14-15 miles) in 1h30 and the last to finish are doing the same in about 2h on average in my class.
how do zones come into play in a race strategy?
