Tri / Triathlon / Triathlons - do they float your boat?

So where to start?

Just signed up for the London Triathlon next July (28th), pretty unfit so am going to concentrate on some running for now to up my cardio fitness as i figure this will benefit both my swimming and riding.

I have seen the beginner to marathon type training programmes on runners world but any good ones out there for triathlons?

Also memberships and clubs, have looked at some sprint tri's next may but some mention BFT membership for discount is there a benefit to having that if i intend on doing a few triathalons next year? If so better to go direct to BFT or via a club as I think it would help a club get some funding. Only problem is trying to fit in with a club's schedule, at could be difficult at the moment (Commuting = training)

BTF membership costs £30 with a club affiliation, and saves £3 - £5 for most races (more if it's a big branded event).

Tritalk has some beginner to Olympic distance plans.

See what your current levels are - do a few shorter distance separate TTs (like a 400m swim, a 5k run, or a 20 km ride). That should give you a baseline and an idea of what might be achievable.

The running is likely to be the hardest one, if you haven't run for a long time, and is the one that might lead to more injuries - So take it slow to start work up to longer distances and speeds.
