Don't usually post on here but was hoping for a bit of running related advice.
I'm not a regular runner but recently ran the GSR half marathon in just over 1hr 42mins, mainly to force me to get off my arse and get fit (or at least fitter). Now that's done I fancy a new challenge and toying with the idea of the Stirling marathon in May, however I have already committed to running a 10k with my wee brother just 7 days after this. Is this as stupid an idea as I'm thinking it is or will a week give me enough time to recover from the full marathon? It's currently 3 days since the half and I'm still struggling to get up the stairs in the office!
