Runners start · local time — Starts run in order from 09:30, beginning with wave 1. The last runner crosses the start line around 10:15 (2026 edition).
On the second Sunday morning in March, the streets of central Cambridge belong to runners for a day.
The start and finish are both on Victoria Avenue, and the race village sets up right beside it on Midsummer Common.
The course loops around the city center, crosses the Cam, heads south into the country lanes of Trumpington and Grantchester, then comes back into town.
St John's, King's, Jesus and Trinity Colleges and the Bridge of Sighs all feature,
though the organizers warn that the cobbles between the stone buildings get slippery in the rain.
The organizers put the total climb at under 320 feet (about 98 meters), and it's a UK Athletics-certified course.
That's why plenty of people choose it for a first half marathon or a shot at a personal best.
By the organizers' count, this is the 15th year, and cumulative finishers have passed 125,000.
More than 50 charities take part, which fills the route with cheer zones, DJ trucks and bands, and in 2026, fundraising topped £1.8 million.
At the finish, you get a finisher medal, a finisher's T-shirt and a snack bag.
One thing worth mentioning is the 2025 race.
It was unusually warm for March, the lines at each aid station were long,
and runner reports say the organizers apologized by email and promised more volunteers, tables and toilets for 2026.
