Lets do this Discount Code Black Friday 2026 - 15% OFF

Lets do this is an online booking platform for endurance sport events, where people can find and register for marathons, triathlons, cycling races and obstacle courses. Its catalogue covers more than 30,000 bookable events in locations around the world, among them well-known races such as the London Marathon and the Brighton Marathon. The company is based in London and serves runners, cyclists and multisport athletes who are looking for their next challenge.

Entrants can search by sport, location or date and book their place through the site. Beyond standard entries, Lets do this sells race gift vouchers that can be redeemed against running, cycling and triathlon events; these are emailed at checkout and typically stay valid for one year from the date of purchase. A referral scheme lets someone new to the platform take a discount on their first booking through a friend's link or code, while the friend earns credit or money back once that booking is completed. Students who verify their status can claim a student discount, and the paid Let's Do This Plus membership bundles race perks, protection and automatic rewards, including a share of race entry fees back and race-day cancellation cover for one event per month.

Event organisers are catered for as well: Lets do this supplies tools for marketing and for managing registration, which are intended to bring in more participants and keep operations running smoothly. Races are grouped by sport and region, so entrants can browse what is coming up nearby or plan a trip to an event further away. The aim is to build a community of sports enthusiasts and help them find their next physical challenge.
