Dorney Lake Marathon Prep

Bring out your best marathon in Autumn 2020 by preparing thoroughly for your big race day. Our Marathon Prep offers the perfect race day rehearsal and long run training in one event with options for 16, 20 or 24 mile distances.

Scheduled 4 weeks before the Virgin Money London Marathon and conveniently before other major marathon events, both in the UK and internationally, we'll provide the ideal conditions to practice your pacing, fuelling and endurance amongst hundreds of other runners to help you head into your marathon feeling prepared and confident.

Set at the spectacular, flat and smooth-surfaced Dorney Lake near Windsor, the course takes you around the perimeter of the water with fuel and water stations placed every 2 miles. Pacers, mile markers and chip-timed results will make it as easy as possible to get your pacing right, so that you can focus on your run and practice refuelling and rehydrating during a race..
