Consistently rated one of the UK’s best Half Marathons over the past five years. Held on quiet country lanes in the scenic Chiltern Hills, an area of outstanding natural beauty, the acclaimed Marlow Half Marathon is a challenging course over the classic 13.1 mile distance, and is a great introduction to this testing but beautiful and rewarding terrain. It's sister event, the Marlow 7, although shorter, shares with its sibling event a lovely, but challenging course that starts and finishes in Marlow.
