Run a full marathon this January in a time of 3:59 to prove your pacing abilities and you'll win the chance to join the Runner's World/New Balance Pace Team to run the 2019 Virgin Money London Marathon.
You'll get a place in the race - pacing a finish time of 3:59 or slower - plus New Balance shoes and kit to run in.
Once you complete your 26.2, Runner's World Pace Team selectors will look at your splits via Summit pacing analysis to see how close you get to the 3:59 goal and how even you can keep your pace, then select the winner, plus five runners-up who will receive a year of Strava Summit membership.

So if want to be a big part of the world's greatest marathon, get ready to fly the flag!
