Pulai Triathlon Tomorrow!!

I'm off to Desaru this afternoon and am doing the 750m/20k/5k Sprint Triathlon in the morning. I'm not really sure how long the swim will take, as it is in open-water, but I'm guessing at 30mins. I like to set a target time for myself, so I reckon on swim 30mins, bike 48mins, run 35mins, 2 x transitions = 2mins, TOTAL = 1h 55mins.
