Cambridge Day Trip or Weekend?

[singtome]

My partner and I live in London and want to do a fairly outdoorsy break/day trip. Thinking walks, cycling, punting, food type thing.

Is 1 day in Cambridge enough (thinking 10am - 6pm) or is a weekend better to see all the sights? We mainly want to be outdoor based because of Covid, so won't be spending time in museums, but do want to see some university buildings.

Do you have an idea of where/how you will cycle? You will not be able to cycle through the colleges themselves.

Cambridge is not a big city but it’s lovely to stay in.
There are some lovely central hotels depending on your budget.
The university arms is gorgeous.
Cambridge when the weather is nice has a lovely vibe in the evening. Especially near the river.
