Thursday, when I last ran, was on our flat (except for grass hill) parkrun course; today, was rough, up and down hill on Diamond Fields Road and Buckmans Lane, so it's difficult (for me!) to compare the two days' training and probably too soon anyhow. In any case, I don't know how to work these details out, so all I can do is write down today's stats and look at them compared to last Thursday's.
8km in 90 mins.
AHR 99 bpm :::: (last week 100 bpm)
MHR 124 bpm ::::(last week 121 bpm)
TE 2.3 = 'Maintaining' :::: (last week 2.0 = 'Maintaining')
