We would like to welcome you to the third edition of ToC100 in 2021. We’ve got an amazing 100 mile route, which is fully closed to all traffic and will see 15,000 riders take to the roads in and around Cambridgeshire on Sunday 6th June 2021.

The flat and fast routes will take in some beautiful scenery, allowing for all ages and abilities to take part. Whether you’re a complete beginner and want to use ToC100 as your 2021 challenge, you need your next opportunity to fundraise for your chosen charity or you’re a sportive expert; ToC100 is perfect for everyone.

We’re very proud of what we believe to be the best sportive in the UK. Not only will you be joining us for traffic free roads, electric atmosphere, Pits Stops filled with sweet and savoury goodies, HIGH5 energy products and water, as well as getting your hands on the ToC finishers medal. We’ll even have exhibitors at the weekend too. This will give you chance to see the latest products, kit, equipment and technology, as well as grab those last minute supplies you may need on your ToC100 experience!

Places on the ToC100, ToC70 and ToC50 start line are limited to 15,000 so enter as soon as possible to avoid any disappointment.
