Dorney Lake Marathon Prep Race - 20 Miles Sports


Bring out your best marathon in Spring 2018 by preparing thoroughly for your big race day.

Scheduled 4 weeks before the Virgin Money London Marathon and conveniently before other major marathon events 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 practicing refuelling and rehydrating during a race.

Pacers will run the entire race, clearly marked with target marathon times 2:30, 2:45, 3:00, 3:15, 3:30, 3:45, 4:00, 4:15, 4:30, 4:45, 5:00, 5:15, 5:30, 5:45, 6:00, 6:15 and 6:30.
Plus, you'll receive a Marathon Prep medal, goody bag with replenishing food and drink, and your chip-timed result as soon as you've crossed the line.

Don't take the chance of having a great marathon race day - take this opportunity to rehearse your:

race day nutrition
race preparation and travel
running in a busy race situation with a marked out course that is new to you
running in all of your marathon race kit
race rehydration and refuelling
recovery and strengthening.

From as little as £16, you can't afford to not prepare for your big day. Due to Dorney Lake capacity and ensuring a great, safe race experience, places are limited. Enter online now.
