Doors will open at 4.30am to allow swimmers to watch the sun come up on the longest day of the year as they bask in the beautiful outdoor pool.

A spokesperson for the Lido said: β€œIn Denmark they burn witches on a bonfire, in Sweden they collect herbs and dance, in Peterborough we swim! What better way to make the most of the extra hours of sunlight than watching the sun light up the city as you swim?”

As well as swimming, breakfast is being served to mark the occasion with a choice of a bacon roll or full English breakfast with a hot drink. Vegetarian options are also available.

Pre-booking is required online at vivacity.org/solstice or you can book your place at the Lido or any Vivacity centre.
