Did it last year in 2:33, my second olympic tri. Didi London the year before in 2:45 but was much fitter for Norwich. Pretty good event...except there were a few lively horses which had escaped onto the road half way round the bike course, had marshalls running everywhere and then the police turned up to sort it out! Swim - the broad was quite warm, nice and clean - no probs. Bike - country roads, not much traffic except the horses! A few drags but no real uphill, more exposed to the wind than any inclines. Remeber undulating in Norwich is flat in most places! Run - path around the lake and across some grassy tracks. Nice course, only one uphill bit for less than a hundred meters. I enjoyed it and will do it again depending on date. You should go for it. My guess is the timing should be pretty similar to London, the transition will be quicker and easier than London. No slippery floors, as the transition area is on grass. My in-laws live within walking distance from the start, so easy enough for me to sort out.
