Fresh from a recent trip to New York with Deb's and the family, Dave looks ahead to the upcoming London marathon. Although not taking part himself this year, Dave had some invaluable advice for runners, as temperatures look set to soar.

Dave also refelcts on the anniversary of his 7 marathons, in 7 days on 7 continents, which he completed back in 2008 and also looks forward to his Great Wall challenge, which he hopes to complete later this year.
