Another day, another run, another 24 hours closer to 66 miles. A light effort was all that was required today: five-ish miles of watch-free, undulating trail in the pleasanter environs of Croydon, taking my weekly total to 30. I have more serious business tomorrow: a run of somewhere between 25 and 35 miles depending on form, motivation and the elements. The plan is to start from Guildford and run east along the North Downs Way (avoiding runners in the eponymous 50-mile race), up and over Box Hill, above Reigate and Redhill, before ending at Caterham or Oxted, depending on levels of enthusiasm. Essentially, I’ll run as far as I can without killing myself before I get fed up.
