Sea Lanes is excited to present the Autumn 5K Swim Challenge 2026. This year we are supporting the charity Friends of Brighton and Hove Hospitals! This is an opportunity to swim 5K but broken down into 50 x 100m intervals. The challenge will run on the morning of Saturday 17th October in our beautiful 50m pool on Brighton seafront.

Swimmers will need to have a good level of endurance and be able to swim and rest off the below times. Pick your speed - we will have 3 lanes available: 
Lane 1: Swim and Rest off 1 min 45 secs per 100m 
Lane 2: Swim and Rest off 2 mins per 100m
Lane 3: Swim and Rest off 2 mins 15 seconds per 100m

Briefing at 08:30AM and swim starting at 9AM.

The pool is heated to 19 degrees year round but as we are an outdoor venue, the temperature can fluctuate. Rashvests and Wetsuits are permitted.
