eek!! to 2weeks to the marathon, i bought a pair of new running shoes 3 days before a half marathon and thought i was mad!! the HM was an off road one and it had been raining and raining ( you know what its been like all summer ) and i knew road trainers wouldnt cut it so went out and bought some, just tried them on in shop and went for it, i wore them all evening and then went for a 3mile run in them the next day and then that was it
I have to say it was very very muddy, i squelched my way round the HM and it was harder than the marathon I had run and I got to mile 12 and I could feel them getting uncomfortable and i took them off vaselined my feet up ( as best as i could with all the mud everywhere ) and got to the end of the race but there is no way I could have done another 13miles in them ( incidentally they are wrecked from the mud and i'm debating now whether i'm ever going to wear them again )
the other thing i bought for my road trainers was heel cushions which fitted nicely into the inside of the trainer could u try those at all with your other trainers?
which marathon are you doing btw?
