Yorkshire Outdoor Swimmers and their coaches present a season of coached open water training sessions at Harthill Reservoir, Carver Way, Harthill, Sheffield, S26 7XB.

For swimmers of all ability levels wanting to prepare for an open water event or just wanting to improve their open water swimming skills.

Our coaches have a wealth of experience and qualifications between them from open water swimming in various environments to triathletes and experienced Ice/cold water swimmers. They can guide you in your first open water experience, on to the start line of your first open water triathlon or give you the tips to take your swim to the next level.

Summer Swimming at Harthill is on Tuesday evening and Saturday afternoon where swimmers can book in for an introductory session, 1:1, or group coached sessions.

If you are entering your first open water swimming event or your first triathlon with an open water swim, you would be well advised to book on to the training programme at least 1 month prior to your event. Don’t leave it until a couple of days before the event. The earlier you can start your training programme – the more prepared you will be.

YOS is all about its members, it is you that makes it great. We are wholly dependent on the time and efforts of its volunteers to allow the club to function. Each swim session requires a team of people to ensure everything runs smoothly. There are lots of roles such as checking swimmers in and out, helping new members, providing safety cover, making tea's and coffee's and lots more.

New volunteers are always made welcome, whatever your skills and abilities we will do our best to make use them! In return for their time and efforts we provide full training, refreshments and free swims in return.
