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

@ Sainsburys Ed - I've only ever done research into IM distance training, for a sprint distance race whats the furthest you would run in training? I didn't do more than 14miles for the Ironman which wasn't ideal but I felt great during the actual race

I not training for sprint distance tris, it's coss training for a marathon I'm doing in September, if I was I'd be training as I would for a 5k I guess, lots of speed work, running up to 10k ish for endurance and a decent amount of strength and conditioning.

Which is essentially what I'm doing for the marathon except my long weekend runs are a lot longer and I'm pretty much ignoring the bike at the moment.

Weekly raining schedule is something like this.
Monday weight training am/pool session pm
Tuesday run speed session
Wednesday weight training session am/ run tempo session pm
Thursday bike speed session (usually a 10 mile tt)
Friday rest
Saturday long run
Sunday long open water swim

Every week day I commute about 5 miles each way by bike.
