Dids opinion of decathlon is probably the same as Steve Ovett's (that pressed Daley's buttons).
OS - you need equipment for Tri, no gadgetry required though. but to be fair some folks make running way more complicated in gadgetry terms than it needs to be in terms of shoes,paces, HR's, schedules, gadgets etc
I like the simplicity of running only on race day when you just need a pair of trainers and not a bike, wettie, bike shoes etc too. But I like the training variety of swim, bike and run, and the challenge of being carp on a bike and in the lido.
8M inc 5 av 6:31 earlier, which is not only the furthest I've run since VLM but also shows I'm getting healthy again.
