Well this workout has become a staple of Coach Glenn's. 5*1600 at 10k effort with 90 second rests.
Tonight I wasn't really feeling it, I can't lie :) Felt really exhausted yesterday and just didn't have that extra gear tonight. Pretty amazed I managed to tackle the first 3 repeats on pace, disappointed with my lackluster 4th repeat, but managed to rally a hair and at least salvage a sub 6 the 5th by ignoring the watch and running an honest hard effort for whatever it was! Not sure but I think had coach been there he probably would have pulled me after the 4th mile, I was just feeling a bit toasted tonight.
I've nailed this workout in the past, and I have also blown up big time, so I will call tonight a wash. Would have liked to have kept that 4th repeat faster, but given just two weeks ago I barely did 8*800 at 2:52s, doing 5*1600 tonight close to that same pace is good enough for me :) Let's hope I am perkier next week though!
