Wonder if any of you can help? I have found that my stamina has disapeared of late. The last race i ran was Blackpool half marathon in june(which i felt i undertrained for)and i have felt tired,un-interested in running and generally feel i can't finish a 3 mile training run. I take a multibionta vitamin and 500mg of vitamin c every day.
Anybody suffered the same....any advice on vitamins etc.Thanks
