is impossible to know but am not sure it's made any difference - that advice is pretty much exactly how my physio treated/rehabbed my other calf last year? maybe was two years?
and I did the walk/run thing to get back to some kind of reasonable mileage, I really took my time over it, at every twinge I've dropped mileage - so went from 35 a week down as far as 10, or even just under, I've had weekly massages from my personal trainer, if I only stretch one thing it's my calves and achilles (on flexibility tests, such as the knee against the wall thing, my calves exceed average expected flexibility by many cms! but a lifetime of yoga so?)
but here I am again, maybe would not have got this far without all that. I dunno. I need a crystal ball to tell me whether it's better to do at least this next half marathon and see how that goes or whether there is time within the next 3 months to fully heal and yet somehow still be marathon ready, or if not ready then ready enough to give it a go
I need a Hester style list! on the plus side I've never had: shin splints, knee troubles (from running) IT band issues, runner's trots
