Got mine for £20 from Blacks - usually use them after a long hard run for recovery but to be honest I think their effect is more psychological. They are also too long in the leg.
Looks like I better keep it secret then if I want to improve - I think most of the good runners were in the half marathon on at the same time. Seriously though I did say I'm not a proper runner and the winner looked about 30 years younger than me, so I'm still pleased with a 2nd.
Wasn't hilly but had a lot of shin deep 'lakes' that the organiser laughingly called puddles and that you had to wade through more than run through. Saw one bloke early on running with his dog have to stop and carry it as it was in danger of drowning!
