Great city and a fun day. Let myself start far too far back for lots of reasons (loo queues included) and ended up 15mins slower than at London and the wrong side of 4hrs. Found it very crowded and hoped to pick up speed after 10/15k but it didn't thin out until 35k.
I like to take on water but the water stations/plastic cups were a disaster area so in hindsight I should have carried. Remind me never to stop for watered down RedBull again. The sponge was useful though.
Not sure I'd do it again but pleased to have done it once. Well done everyone that ran.
