Tell you what Samir. 5 hours will easily get you from Ealing to Reading with something to spare. Why don't you run to Reading on the saturday morning, run Reading parkrun, then run home. I'm in Reading, and i wonder if Jonny might be back in the holidays. You could put us both to the sword within the middle of a 10 hour run! Imagine the kudos!
One of my pet hates is, when April comes round, seeing all these celebrities from Holby City or GMTV puffing and panting on my TV screen. I certainly don't like it when Hazel Irvine interviews them half way through.
