Fabulous Course

Ran this last year and it was a fantastic course along the Thames, zig-zagging across bridges and through the villages between Windsor and Marlow... this year the other way - so it's downhill this year... right..?!?! Well organised event with plenty of water stations... but could have done with some sweets etc. Also at finish, more water needed as restricted to only 1 bottle of water... Medal was superb and my best one to date, goodie bag was OK... I think, can't quite recall.
