Yesterday morning I did a interval training class at the gym - I'd never done the class before and it was brutal ! Now I ache ALL OVER and struggling to even lift my arms ! problem is I have a marathon to run on Sunday although I think I should feel back to normal by then (right?) is there anything I can do to speed up the recovery ? Should I just rest or shall I maybe have a gentle swim tomorrow ?

Thanks in advance

p.s please don't preach about how I shouldn't have done the class ect I am now fully aware of that fact
