Week 10, day 5 – threshold intervals

I had dined possibly a little too well the previous night (friend’s birthday) and not had enough sleep (creaky office chair), but the weather was good and the plan said I had to do threshold intervals, so out I went.

It was 6 efforts of 5 minutes each, with a minute recovery between each effort, and I was pleased with the pace I was able to maintain fairly comfortably within my ‘threshold’ heart rate zone (159-173bpm). Looking back at the data it appears that my consistency hasn’t abandoned me with the efforts being run at 4:26, 4:26, 4:26, 4:27, 4:26 and 4:18 min/km pace (which in min/mile pace is 7:08, 7:08, 7:08, 7:09, 7:08 and 6:55).

A nice recovery run and core class tomorrow, then an amended long run on Sunday (following discussion with my coach) which now has 45 minutes of marathon pace in the scheduled 2 and a half hours, eek.
