I don't know anything about osteopaths to be honest, so not sure. It sounds like the fact that you are sitting all day is what is making it worse as I suspect it's tightening up while you are sat still. How often do you get up from your desk to walk about it bit? Do you do your exercises at work, say in your lunch break? How long do you hold each stretch for?
If you were still feeling a niggle it wasn't wise to increase the distance really. Doctors won't really want to know as it's only to do with you running, unless it's affecting your mental health or something. So what advice did the physio give you about stopping it reoccurring? Are you doing any exercises you were given before or after a run?
Maybe see a sports therapist instead of a physio? Mine is great at diagnosing problems; I also get a massage that releases any knotty or tight areas and she'll give me exercises to help with whatever the issue is.
After a two week rest are you going straight back out and doing the mileage you were doing before? Are you stretching properly (2 x 30 second stretches of each stretch when you get back from a run)? Have you been told what the issue is by the physio and been given rehab exercises or instructions?
Morning isn't really practical Cake as I'm coming from Norfolk and I didn't want to then be stuck in London all day with nothing to do! From what I can gather this year a lot of the freebies seem to be gels and stuff, which I don't use anyway
Forgot I need to post a picture, although my running vest also has my name on it now in sparkly white letters!
When we went last year on the Saturday afternoon there weren't any freebies and most of the stalls seemed to be either the gold bond place ones or ones that wanted you to buy something, so I didn't really see the point in bothering again this year! Want to get a Bondi headband from the DMP stall, but that's it really
