London Aquathlon - 31 October 2026
The London Aquathlon on 31 October 2026 is a swim and run event at the London Aquatics Centre in Queen Elizabeth Olympic Park, London. The format combines an indoor pool swim followed by a measured park run.
Event distances:
- 400 m pool swim (4 lengths / 8 laps)
- 5 km measured run around South Park with views of the London Stadium
Entries are open to participants aged 15 and over. The race starts with the pool swim and continues onto the run course, with each kilometre on the run marked by distance flags.
Included in the entry are a unique themed medal, free race photos, chip-timed results and post-race goodies. The course is supported by marshals who will guide and cheer participants, and there is an event village with food and drink options and partner giveaways at the finish area.
The organiser, RunThrough, states it has researched participant priorities and identifies sustainability as a growing focus. An event t-shirt with the event logo is available at a discounted price when added to the entry. Visit the organization's website for the most recent information.
