On Thursdays for the next 3 weeks I will be trying to do blocks of 15-20 minutes at threshold. This week I was a little crunched for time but managed to get both of them in. The large blips in each graph reflect the turnarounds I had to do on Riverside Drive where my course is only 5 miles one way. Both of the intervals went well but the second was a bit better than the first because it included the long hill on Eves Road up from the river.
I was satisfied with the results and my average power for each was 277w and 286w respectively which was in my training zone of 267-310w.
