A mate of mine ex donkey walloper is attempting the Arch to Arc race on the 17th of Aug. This is a race against the clock from marble Arch to the Arc de Triumph. Arch to Dover run 87 miles, Dover to Frog Swim 22 miles, Calais to Paris cycle 180km +. I'm too thick to do the linky thing, but he has a web site called Tricoach. Worth a look.
