Hey there Bubbleboy
also had one season or so of experience with tri's. but i'm really keen to do more. i kinda got it the wrong way round - did the half IM at Coomera as my first tri to join a mate who was training more seriously. that was overall easier than the marathon i had done 4 months earlier, but had a couple of difficult periods. i had a bike for only 8 weeks and not done many longer rides. i hadn't swum for 5 years until the event itself, but that still worked out ok. despite that finished about half way in the field - the point being there' always going to be plenty either side of you so just get in and do it mate. don't worry about the equipment, they should service the bike. PM me if you have any probs, 'cause my mate could probably do it for you in the garage depending on the problem.
i'm not the best one to get a program off becasue i basically stick to my running program , do a couple of rides here and there plus some wind trainer sessions, and just do 5-6 swim sessions. i'm finding form the race stats that i'm about 50% in the fled in the swim, 50% in the ride and about 20% in the field for the run. that's becasue it's what i focus on more. they say run 3, ride 3, swim 3 in a week, but if you love your running drop a bike etc. seem like the faster folks spend more time ont eh bike but it's hard ot find the time. i don't thin it's a tiredness issue because they are good cross training so long as you sleep well, more of a time issue.
look forward to chewing the fat about this one at some PCRG sessions when i get back there. will be doing a lot them this summer i hope so will be fun to catch up. there's a bunch of Brissie CRs all in the same sort of range who are relatively new at it and sharing experiences etc .
hook in, it's fun and a lot easier than what you just did at GCM

(well done again on that!)
cheers
