The Round 100

The Round 100

This is not just another 100-miler.

The Round 100 is a unique 100-mile trail ultra following the historic Leicestershire Round, a waymarked route that circles the entire county through rolling countryside, ancient trails, farmland, woodland, country lanes and riverside paths.

This is the inaugural solo Round 100 — the first time this historic route has ever been raced as a complete ultra-marathon. When you cross that finish line, you won't just have completed a 100-mile ultra — you'll have become part of the history of the Leicestershire Round itself.

A UTMB Index Race

The Round 100 is an official UTMB Index Race in the 100M category.

The UTMB Index is an international performance-rating system run by UTMB Group, designed to let runners, race organisers and fans compare performances fairly across races with wildly different distances, elevation profiles and terrain. Finish an Index race and you're given a UTMB Index Score for that specific result, calculated from your finish time weighted against the course's own difficulty. Your overall UTMB Index reflects your best scores across races within that distance category.

Finish the TR100 and your result counts towards your official UTMB Index in the 100M category — a recognised, internationally comparable marker of performance, useful if you're building towards entry into other UTMB World Series races.

Please note: as an Index race, the TR100 contributes to your UTMB Index, but does not award Running Stones towards the UTMB Mont-Blanc lottery — those are earned only at UTMB World Series events.

Team Relay Option

Run the Leicestershire Round as a team!

The Round 100 Team Relay allows teams of 4 runners to complete the route together. Each runner must complete a minimum of 20 miles to qualify for a finisher's medal.

Team relay changeovers must only be made at designated checkpoints, in the presence of a member of the Beacon Race team. If teams are seen to be transferring the GPS tracker to another team member outside of a designated checkpoint they will be disqualified.

The only time more than one team member can be on the course is the final mile. There will be a squad meet-up point where teams can run the final stretch together and cross the finish line as one.

All members of the team must carry all mandatory kit at all times.

Each team is responsible for their own travel between checkpoints for changeovers, and for their individual changeover location and duration strategy.

Checkpoints & Support

There are 9 checkpoints during the race. Each checkpoint will provide refreshments including cola, electrolytes, water and juice, as well as a variety of sandwiches, salted potatoes, fruit, snacks, crisps and biscuits. We do our best to provide a range of food for Vegetarian & Vegan diets too.

We'll also have a Medic, First Responder or a 1st Aider available at each checkpoint.

Cut-off times per checkpoint are implemented by Beacon Race Events to ensure the safe and proper running of the event. Checkpoint cut-off times will be strictly enforced. There is a 32 hour cut-off time for the event.

Checkpoint locations and cut-off times: TBC
Full checkpoint details will be published here as soon as they are confirmed.

Safety + Rules

If you see a runner experiencing difficulties during the TR100 please inform Checkpoint Marshals or Race HQ. Each runner should save Race HQ mobile numbers on their mobile phone.

No roads are closed en route as this is a trail race, so please exercise due diligence and care at road crossings. This will mean that participants may have to slow, or possibly stop, to cross roads safely.

There are certain sections that lead onto country road and/or road crossings. Due to the length of the route it will not be possible to completely marshal a 100 mile route. It is the role of the entrant to be self-sufficient and exercise caution. Any emergency situations will be dealt with by the Chief Medical Officer.

No pacers or support runners are allowed at this event.

This is an England Athletics / Trail Running Association affiliated event. This event will be organised and run under their rules and covered by their insurance.
