Run into winter with a half marathon around the scenic Dorney Lake. This is the UK's flattest half marathon course and is great for runners looking for the consistency of a lapped course. Come along for that near-certain PB and bespoke finisher's medal.

  • Did the Half Marathon in 2018

    This was my first running event ever and I really enjoyed it. Everyone was really friendly- only points of constructive criticism would be to have a MUCH clearer website and make it much easier to find photos and results. It took me days if searching through the web to find anything ! Also, the photos taken were pretty bad but that's a minor thing ! Overall, really fun and friendly event
  • Did the Half Marathon in 2018

    Good experience although it would have been useful to have distance markers. This was a view shared by others.
  • Did the Half Marathon in 2018

    I had all the info I needed
  • Did the Half Marathon in 2018

    Lovely fast, flat, PB potential course. Whilst laps aren't the most fun thing, it enables easy pacing and a chance for supporters to see you and cheer you on multiple occasions. Get there early if you want to relax as there will likely be a queue for registration and the toilets.
  • Did the Half Marathon in 2018

    Great - efficient, friendly, fast course
  • Did the Half Marathon in 2018

    Lack of toilets and bottled water at finish
  • Did the Half Marathon in 2018

    Getting the results could be a little easier.
