That one sounds like its alot easier than the 2 tri's I did which I believe were Supersprints 400m swim 10km bike and km run. It was run by the small college I worked at so it wasn't competitive in general. I never could get through the swimming part because I didn't really train much. The first year it was really windy so waves would wash over you and so doing a backstroke was impossible. I got farther the 2nd year, btu it was pretty windy that year too. IMO the cycling is the easiest part (because I cycle LOL) and the run you can always walk and then run in spurts which is what I did. You event features the cycling which is your thing. If you know you can swim that distance no problem I wouldn't worry too much, but you might want to swim a few times beforehand. I really should train and try it again because I kinda gave up because i could never get myself in th pool enough to be ready.
