Open water swim sessions

Please note: Due to Covid-19 Ardingly Reservoir swim sessions are strictly limited to members only and must be pre-booked.

Please use our event booking page to book your session.

Open water swimming is extremely popular with Club Members and takes place from early May to the end of September (depending on water temperature).  To enable you to take part in open water swimming sessions with the club, you must:

  • Be a current member of the Club
  • Accepted the indemnity waiver during registration or under your details page
  • Wear a wetsuit and visible swim cap
  • Be prepared to take a turn in the kayak or spot on the pontoon (Ardingly reservoir only - see below)

Taster Sessions

  • We are currently unable to offer taster sessions. We will review this as the Covid-19 guidelines change. 

Every open water swimmer must accept the indemnity form during registration on the website for the forthcoming season/year and read the risk assessments and club policies.  The reservoir authorities require new indemnity acceptance each year from each swimmer - those completed last year are redundant.

Our venue is at: 

Ardingly reservoir

We have two weekly sessions run by the Club

  • Saturday mornings 08:30-10:00
  • Tuesday evenings   18:00-19:30

The cost for members is £4.00 per swim.  You can buy credits on the website on your details page. Safety cover, changing facilities and showers are available. 


To keep everyone safe we have a spotter on the jetty and kayakers on the water accompanying swimmers. We operate a rota system and everyone that swims will be expected to kayak or spot on the jetty at some point. We use a separate web application called Dutyman to manage the rota

  • You will be emailed your time to kayak/spot from Dutyman
  • Please either confirm your duties or arrange to swap with another member
  • You can also login directly to Dutyman here Dutyman MSTC Rota 
  • Please use the reminder feature on dutyman if you forgot your password.
  • If you do not receive any emails there are some tips to help  dutyman email tips

If you are attending the swim sessions or working the rota please check out our safety video before coming to the reservoir.
