Join the Grimsby Water Rats on a classic British bank holiday weekend in their fifth revival of this classic British swim challenge.  Choose from a mixture of distances to suit all swimmers - including out new for 2020 5 km challenge.  

New to open water swimming?  Try a lap of Grimsby’s historic Alexandra Dock (first used in 1880) and [possibly] swim alongside some of the largest car cargo transporter ships in Europe.  Or go for a PB with our 2 mile swim – if you are wanting more of an end of season challenge try our new for 2020 5Km swim or go the whole hog and enter our 10Km marathon swim.

Enter as a team of three in a single distance and see if your team can walk away with a team challenge trophy.  Teams can come from established sports clubs or simply get a team together and get a team name.  Winning teams are simply the fastest combined time for all three team members to cross the line.

A perfect family outing or future club calendar regular to get together, have fun and challenge yourself to swim in a unique environment betwixt lake, river and sea.

This year the Great Grimsby Dock Challenge is being held in conjunction with the 1st annual Harbor Place Raft Race.  While not swimming, watch the fun as the raft riders battle it out to be the fastest on the docks (while staying in one piece) or browse the swimming and local producers stalls while enjoying a refreshing drink from the Grimsby and Cleethorpes Yacht Club clubhouse.

Come join the Grimsby Water Rats in a celebration of swimming and a day to remember.

Changing facilities / wetsuit rinse / parking (included in entry) / refreshments / new friends / funky PA / prizes and a very loud starting canon to boot.
