Sussex Open Water Championships 2026

Mercers Lake, RH1 4EU

Sunday 28th June 2026

Following the success of our 2025 Open Water Championships we have again taken the opportunity to join forces with the South East Region and have designated the regional Open Water Championships as the host event for our own Championships in 2026.
 
Every Age Group swimmer who is affiliated to a Sussex club will automatically qualify for the Sussex Open Water Championships being held at Mercers Lake on Sunday 28th June. By entering the event they will also swim for qualification for the National Open Water Championships. 
 
Sussex have designated the 2km, 3km & 5km Age Group events as our Championships events and will be offering both Championship and Age Group medals to Sussex swimmers. The results from the regional event will be used to identify Sussex Junior and Senior Champions and also the basis for the awarding of Age Group medals.
 
Supplementary conditions
 
In addition the event has a 1km novice race and 2km & 3km exclusive events for Masters.
