For those not running the London Marathon, a great alternative in a chance to enjoy a social Tour de Chesham this Sunday.
Meeting at 9.30am at the car park at the Moor Chesham HP5 1SE the routes circle Chesham whilst remaining largely rural. There are two options , 7.6 and 10.0 miles. Full details are on the web site ( Route Maps drop down ) under reference C4 Tour de Chesham 7.6 &10 miles. There are PDF, GPX and OS files for paper and tech options to download.
Should be dryer under foot.
