2 mile warm-up then did 4 x 1000m repeats with 2:00 minutes recovery
1-3:27 Felt pretty good
2-3:27 Still feeling good
3-3:28 Not bad, got a drink after this repeat, big mistake
4-3:36- Stomach cramping and not feeling good.
2 mile cool-down. I was going to do 5 repeats, but was really hurting after the 4th so called it a day.
