What I set out to do was:
12 mins warm-up .... I did 14mins.
6 x 30 seconds. 30 secs RI .. did these on long incline Renwick Drive
4 x 3.5 minutes hard .. did these on level ground in Scarlet Street
RI 90 secs to 4 minutes
I will have to look into why Garmin is refusing to work; cold weather? I need it to work properly on Sunday! Hope to find out because this morning's activities sent my blood pressure sky high for sure!
