I was out on a ride today which is a loop of 28 miles and about 2100 ft of climbing in 3 hills. On the climbs I was pushing my FTP power of about 265w and sometimes over that (which is where I went wrong, I spent 20% of the ride at threshold and 13% at VO2 Max) and my HR was about 165 (on the climbs) which is my LT. The last 9 miles is a false flat, and I was exhausted, my HR was average was 155 and my average power was 194w. I was sitting on with my friend and I could just hang on.
I am guessing that I went too hard on the hills but I am wondering physically what happened? I have only been riding with my Power Meter for about a week, so keeping my power at a reasonable variance is still quite new.
Insight is appreciated.
BTW, if it matters I am 39 and weight 183lbs (or 83kg) I had a goo about half way and a bottle of gatorade and 1 bottle of water on the ride.
