Matt Todman will be answering your questions live on runnersworld.co.uk this Friday, 5th April from 1 – 2pm.

Are you running a half or full marathon? Maybe getting a few niggles but refuse to give up the training? Or maybe the spring air and too much chocolate has inspired you to pound the pavements and you need to ask for some expert advice.

Go to the runnersworld forum and ask away…
