How to organise a sponsor swim

A sponsor swim combines an open-water challenge with fundraising, so you need to plan the course and the event administration together. Start by securing the swimming location, setting the distance and checking permits, insurance and water safety requirements. Then open registration, approach sponsors and build a volunteer rota around the safety plan. In the final week, confirm every swimmer, number the entries, prepare starter packs and check that route marking, first aid and communications are ready.

Tips

Set the route and distance before opening registration. Participants need to know the course length, start and finish points, and any access restrictions when they sign up.
Complete the safety plan before recruiting volunteers. Allocate supervision and a lifeguard post to the route, and make sure the first-aid kit, life rings, lifebuoys and radios are assigned to named people.
Give registration a clear closing point, ideally 3–5 days before the swim. Use the final list to check dietary requirements, assign start numbers and prepare one starter pack per participant.
Walk the route and access points during the week before the event. Check where signs, cord lines, tents, tables and chairs will go, and allow extra time for setup if equipment must be carried from a vehicle.
Test the event-day communications before swimmers arrive. Check the wireless microphone, speaker, stopwatch, timing chips, tablet, power supplies and two-way radios rather than discovering a missing cable at the start.

Frequently asked questions

How far in advance should I organise a sponsor swim?: Allow at least 8–12 weeks for a small sponsor swim. This gives you time to reserve the swimming location, apply for permits, arrange insurance and safety cover, open registration and secure sponsors.
How do I plan safety cover for a sponsor swim?: Start with the route and water conditions, then define supervision points, a lifeguard post, emergency access and communication procedures. Finish the written safety plan at least 2 weeks before the event so volunteers can be briefed and equipment can be allocated.
When should registration close for a sponsor swim?: Close online registration 3–5 days before the swim if you need to print numbers and prepare starter packs. Keep the participant list with you on event day and allow time for a final check of names and dietary requirements.
What should I prepare the day before a sponsor swim?: Assemble starter packs, fill coolers, print the programme and route signs, check the volunteer schedule and collect the equipment. Set aside 2–3 hours for a route and access check, including power, tables, tents, safety equipment and communication devices.
