The Lake

Here’s where all our informal stuff used to happen, Lake 1 at Action Watersports (address below), used for various forms of getting wet with the help of an engine for most of the week.

From July 2019 we have moved just down the (same) road to Herons Park.
Choose a later home-page event tile to see more about this.

The lake is a bit over 600m long or 500m from the jetty to the far end.  If your goggles are up to it, you might spot some distance markers on the West bank (no, not in the Middle-East!).  The lake is not very deep, so it warms up at a reasonable pace in a reasonable Spring and it tastes a lot better than the sea, though lake-tasting is not endorsed by the management.  Goggles should be considered a must-have for open-water swimming and a bright swim cap is a good idea.

2019 Informal evening sprint tri’s
These occur at the lake, several times a year. We fit them in when we can. They are loads of fun, ideal for your first-ever event or for testing new gear or race strategies or just having a nice laid-back training session.
This list can change during the year, so check back here from time to time.

Sprint Tri distances are 500m lake swim, 20k bike to Camber (holiday camp roundabout) and back, 5.2k run.
Supersprint is 300m swim, 14k bike turns just before the seafront wall, and back, 3k run down the road and back.
Registration (on the day only, cash only please) from 5:00pm (mostly), £20 (no concessions for the evening events, sorry).
See table above for times and distances. Start times vary because of available daylight.

Open water swim nights take place in the lake, roughly during British Summer Time, on Tuesdays between 5:30 pm and 7 pm, and Thursdays between 6:30pm and 8pm.  A nominal fee of £6 is charged and you will be asked to sign in for safety reasons.  You may want a wet-suit and a swim cap, preferably a bright one so you can be spotted at a distance. A leisure wet-suit can be hired for £5.  These are not designed for swimming but I used one, several times before I bought a proper swimming version and they are perfectly adequate to find out whether you want to invest in a proper swimming model.  Talk to any of the regulars if you want some advice.  Goggles should be considered a must-have for open-water swimming. There is always someone on the jetty and a jet ski on hand should anyone get into difficulty but as the regular route up and down the lake is used by everyone we also watch out for each other. “Keep right” (swim anti-clockwise) is the usual rule unless instructed otherwise.
