If you are attending one of my training camps and require accommodation, take a look at these options.
If you want cheap and cheerful, there is a Premier Inn about 5 mins drive / 30 mins walk away…
Another cheap option is the Youth Hostel very close to the train station. From here you can catch a bus to the sports centre, which takes around 25 mins.
Or there are 3 Travelodges all about 3-4 miles from the sports centre.
A little bit further afield is Madingley Hall. This is about 3 miles from the Sports Centre.
Another option, a few minutes drive from the sports centre, is the Hyatt Centric Cambridge. Or you can book a studio or two bedroom apartment at Turing Locke, which is also a few minutes drive from the sports centre.
There are lots more hotels and B&B options too in central Cambridge. You could also look on Airbnb. There are a few properties close-ish to the sports centre which may be available.
