Hard 1kers and 400's

Not feeling the best tonight, but I heard we were in for a hard session. We did a 1km rep, with 1 minute recovery, then a 400m 3 times. I was running with Haftu and Tom. First 1k was in 3:01 and I was feeling ok, then the 400 and I did it in 67s. Next 1km did it in 3:10 and by this time I wasn't feeling great. Next 400 was in 70s. Again wasn't feeling it. Next 1km I just broke, I ran a 3:15. Haftu ended up running a 2:55. Great session from Haftu. Me, I just want to focus on beating some PB's now. I'll try and put in some hard work in now. Looking forward to racing soon.
