Gawd the things you can find on google images ;-)
Yes, you've guessed it, it was fartlek tonight.
I generally view this as the fairy of rep sessions. Verging on the not-to-bad side of tough. Unfortunately tonight, I was teamed up with three packs above me. Therefore I was the goose breathing out my ears at the back of the group. Managed to keep up for bursts, varying from 100m, two minutes, 800m, 200m, 1000m, more random sprints and hungry hill to finish. It was only on the longer reps that I noticed a gap. Jill (coach for the evening) said that "it was a better session, as the runners were closer together. No waiting about". I'll take that as a compliment. Cheers, FB ;-)
