Hill Repeats

I went back to an old hill I used whilst training for 6FT back in 2002. It's 550m long with a nice gradient, a good leg strengthener. 3km warm up and then 6 reps as follows:

2:46
2:47
2:48
2:49
2:46
2:47

2.5km warm down back to the office.
Humid and warm, was pretty wasted after the set.
11.5km-59mins
