Bloomberg Square Mile Relay - London route

Set amidst London’s infamous Square Mile runners challenge each other for position as they navigate tight turns, sharp bends, and flights of stairs on this unique one mile (1.6km) route, synonymous with the Bloomberg Square Mile Relay. The stunning skyline provides a dramatic backdrop to the race course that challenges returning runners on the start line, but also offers a unique, fun and exciting race for first-time participants. Check out the route that runners took for the 12th Bloomberg Square Mile Relay in London earlier this year.


1. Every team must complete 10 laps of the designated one-mile (1.6km) course.

2. There can only be one participant per team on the course at any given time.

3. Should any participant wish to walk instead of run during their lap, always keep to the side of the course to prevent blocking other participants.

4. Your race baton contains your timing chip. Participants can only pass the baton by hand to their own team members in the transition area opposite the race pens – throwing, rolling or kicking the baton is not allowed.

5. After handing the baton to their team member, the participant must immediately move into the Finish Area. The last participant must return their team baton to staff in the finish area.

6. Each participant is required to display their bib number clearly throughout the race on the front of their t-shirt or vest.

No appeals are allowed. The Race Organiser’s decision is final.

London - The Extra Mile

The Extra Mile helps participants of the Bloomberg Square Mile Relay contribute to their city in a bigger, better way. We are delighted to be working with Greenhouse Sports as The Extra Mile Partner in 2019.

Simply by participating in the race, 25% of your team’s race fee will be donated to invest in projects delivered by Greenhouse Sports in London. The best part is, you get to help choose where those funds go by choosing a cause you care about, and running for it. When you complete your personal profile on our website you will choose one of three causes to run for, from Inclusion, Education or Empowering Women & Girls. Then, on race night, your lap in the Bloomberg Square Mile Relay won’t just be for your team, but for your Extra Mile cause too.

The cause with the quickest average time will win a minimum donation of US$20,000. Funds will be used to address the winning cause across a year-long project.

​What are the changing facilities?

There are changing rooms onsite, and a cloakroom to leave your bags, but please note there are no showers available. We recommend that runners arrive ready to run!

How does the event work?

This is a fully immersive team-building event combining a corporate team relay race, hospitality and after-party. For the race, there are ten runners on every team, each of whom run a one-mile lap, relay style. The fastest team to complete the full ten miles wins! Following the race all runners receive hospitality and access to the after-party in the race village.

Can I register a team now and recruit team members later?

Only one person needs to enter and complete payment for the team. Following your completed team entry you will be able to submit all 10 runners on your team in your team’s profile section of the website.

Who is allowed to participate?

Team registration is only open to corporations. Each team is required to have 10 runners to take part in the race. However, we invite and encourage all colleagues, friends and family to come and cheer you on and enjoy the celebrations.

What if we don’t have enough people for a team?

Each team is required to have 10 runners to take part in the race. However, in exceptional circumstances (due to last minute illness or injury) the minimum number of people per team permitted is 8. In this situation we allow 2 members of the team to run twice. We would advise you to have reserves that would be willing to step in if you find yourself with last minute dropouts as refunds are not available.

Please note that a minimum of 8 runners in each team must be employed by the corporation entering a team in the race. However, if a corporation has less than 20 employees, they are able to group together with one other company that also has less than 20 employees in order to form a team, but at least 4 employees from the registered corporation must still participate in that team (see booking terms and conditions for further details).

I haven't managed to get the whole team to sign the Injury Waiver Form –
what should I do?

The Injury Waiver is a document that must be ‘accepted’ online by each runner in their profile section in order to participate in the race. The Team Captain must also send through the names of the runners in the correct running order. If you are missing any signatures we are able to accept them at the registration tent at event.
