Join us for our latest audio guided  challenge, as we invite you to run through a unique half marathon route taking in all 31 of Cambridge's colleges, as well as some other fantastic sights from one of the most picturesque cities in the UK. 
​
Your GPS location will trigger directions through your headphones, as well as commentary throughout as we explain the history of the colleges that you're running past, as well as pointing out other spectacular sights on the route. ​
​
Sign up today and take on the challenge, at your own pace, between Monday 2nd March and 31st December 2026, with an optional finisher medal upon completion.
