Running 1:42:26 
Made a late decision to race the Surrey Slog. Roughly half-marathon distance route featuring mulitple hilly loops around Holmbury Hill and almost no flat running at all.
Finished somewhere around 20th-30th at a guess?
Struggled on a couple of the long drag ascents in the middle but otherwise had an alright run. Was aiming for 1hr40 but that was a fairly arbitrary time so not too fussed about missing it.
Gels at 30mins and 60mins. About right.
