Just entered 2014 Brighton. £50 + rip off booking fee. £10 cheaper for first 2,000. £60 after. Now to shave that time down from 4:08:47 to a more respectable 3:40:00.
A full triathlon is the Olympic distance. 1.5 kilometres (0.93 mi) swim, 40 kilometres (25 mi) bike, 10 kilometres (6.2 mi) run. The Marina is less but still demanding though due to the hilly bike ride!
