Mountain Bike (Roads) 2:00:23 [3] 30.6 mi (15.3 mph)
ahr:146
Well, this was mentally difficult for me, and I guess I did not rise to the challenge. Got my zones and today was the first day to employ them. I was nervous that I wouldn't be able to hit the desired heartrate today, so I did go into it in the wrong place mentally. I was supposed to do the middle hour at "tempo" pace, which meant 157-168 based on my test. I don't even get that average on the slaughterfest when I have the fear of getting dropped to get me to hang on.
Anyway, first 30 minutes: avg 129. This is below Z2 according to my test, but I went by feel anyway because I thought I was still putting in a decent effort for a warm-up
0:30-1:30 - avg 146 I was trying to go hard, and I thought I was. My legs were burning, I was breathing hard, but the HR just wouldn't go up - I hit 157 on climbs, and the best I could seem to sustain for any time was 153, but this was at the beginning. Often found it dropping down and I would have to push to try to get the HR up again. Seemed like the legs were the limiter here.
1:30-2:00 - avg 124 My legs were definitely feeling the 1 previous hour.
I feel like a failure because I couldn't even get out of zone 2. I have no idea how I was getting a HR of 166 on average for that 20 minute time trial and I couldn't even hit it at all today. Equipment difference?
