You can find all the information you need to know on the Ultra Challenge website too.

Ultra Challenges are physical events, where you can choose to walk, jog or run a distance of 10km –25km. The Event Organisers welcome participants of all abilities who are confident in their ability to participate, however must ensure everyone is clear on the requirements and accessibility restrictions of the route. 

If you have any accessibility concerns or questions you can contact Action Challenge directly to discuss requirements and they'd be happy to support you.

The route starts at the Oval Cricket Ground  and has good tube and train links, plenty of toilets, medics, hot food and drink – and some heat if there’s a chill in the air.

The trek then heads along the Thames and loops through the heart of the Capital, highlighting London's landmarks!

There is no parking or dedicated drop off area at the start.

The closest tube stations are the Oval (Northern Line) and Vauxhall (Victoria Line & over ground) which are both about a 10 minute walk to the start (there will be signs pointing
to the start area).

The event organisers recommend that you bring a small rucksack (20-30 litres max) to carry all you’ll need for the
walk (extra clothes / water / phone etc).

There will be baggage storage
at The Oval (start/finish) for any larger bags you may have and a cost per item is payable by cash or card on the day - 20kg/80L max size.

Changing rooms will also be available.

Of course you can! Everyone must register individually as the event organisers require personal details and declarations. Within the form you can choose to ‘Create’ or ‘Join’ a Team.

Teams can be of any size and members can opt for the same or different funding options / distances.

• When you create a Team  you become the Team Captain. You need a Team Name and a password for others to join. Then you can invite your friends and family to join you!
• Other people can join the Team as they register, by searching for the Team Name and using the Password
