Run the Thames Bridges Half Marathon

Run a half marathon over the Thames bridges on a self-guided audio tour, triggered by your GPS

16 FEB 2024 - 31 OCT 2024


We challenge you to run a half marathon over the Thames bridges in a unique self-guided audio tour that takes you from Tower Bridge to Putney.

With 17 bridges in total, your GPS location will trigger directions, along with audio commentary that celebrates the history of the glorious River Thames, its bridges and the development of our capital along its banks.

As you cross over every bridge possible along the route, you'll enjoy some of the best views of London, discover their history and get a unique training run in the bag.

Sign up today and take on the challenge at any time between now and 31st October 2024 with an optional finisher medal upon completion.

  • 1. How fast do I need to be?
    All fitness levels are welcome. Each tour has a guide pace to keep you in your comfort zone. We operate on a "no one gets left behind basis" which means that we'll always run at the pace of the gentlest person in our lovely group. So please don't be nervous about joining us. But also, don't be afraid of signing up for a merrily medium or festively fast pace and the gentle jingle is often very gentle. There are also walking tours available of the 5k Christmas lights tour.
  • 2. Do you have a bag drop?
    Unfortunately we do not have a bag drop, especially with the tour starting and ending in different parts of London. Our tours are not races - so we advice packing light and bringing a running backpack for your essentials. If you need to store any items, we recommend using Luggage Hero before you come to your tour.
  • 3. What do I need to bring with me?
    Your ticket on your phone (we don't need a paper copy), water if you usually run with it. Wear warmer clothes than you usually would for a run of the length of your tour - we will be stopping around the run to for twinkly lights and festive history. Of course, we highly recommend all the Christmas fancy dress.
  • 4. Is the Christmas lights tour suitable for children?
    Yes - children are welcome, as long as they're accompanied by an adult who takes full responsibility for their safety whilst on the tour. Accompanied children are welcome at all our tours, as long as they're comfortable with the guide pace, but we do have 2 Family Special dates for the 5k Christmas lights tour, so you can bring little ones and know there are plenty of others there too.
