Today’s scheduled training session was to be a “hard distance” of anywhere from 5K up. I chose to do a 30 minute timed session with a goal of making a new season best result which would be well over 7K.
I also thought it would be nice, if the session could be used to get a new measure of LTHR. It’s possible to get a very accurate LTHR reading if a 30 minute session is raced and then the average heart rate is calculated for the last 10 minutes. That didn’t work out, because I didn’t do the 30 minutes hard enough. (I haven’t raced much lately and so I didn’t know how fast I could go for 30 minutes. It turned out that I had a lot of energy left so this 30 minutes would give a very low and inaccurate reading for LTHR. At any rate it felt good and was refreshing.
I did a 1250 meter warmup and a 1250 meter warm down. Straps were loose. DF was 140.
Happy trails to you.
