Knew it would be painful and it was.
Started off too fast and suffered somewhat from 6k onwards. Ideal conditions though - very little breeze and warm enough...light rain.
2k in 7:20, 5k in 19:20 and slower after.
Got cuffed by DG by about 1 minute but happy enough.

100th/3044, 6th o/50 (1st o/50 was 5th in 33:46!)
Met John Robertson at the finish - probably last saw him about 30+ years ago when both running for the Uni Haries. He always beat me then, didn't today, got him by 27 seconds..:-)
