20.5 done and dusted, in roughly marathon target finish time. Started nice and slow, then after 7 miles or so I found myself trailing a guy running just a bit quicker than I was, so I decided to follow. 3 miles and a lot of hard work later I finally caught him, to find out he's a 2:50 guy putting in few miles of MP in the middle of his run. Ouch!
He said he knew me from here but I got his real name, not his forum one so thanks for the tow, feel free to tell met stop being a numpty if I do it again. The rest of the run was OK, but I paid for my ill discipline on the last mile uphill home. Hard work.
