Quick answers
Which local rescue or training agency should I check first?
Use the local lens: coastguard/federation norms and the shop briefing for that bay — not a blog visibility claim.
When did the Olympics add marathon swimming?
The 10 km open-water event debuted at the 2008 Beijing Games, held at the Shunyi rowing-canoeing park.
Who first swam the English Channel?
Matthew Webb swam Dover to Calais in 1875. The Channel remains the most famous ratifying-body swim, under rules later formalised by the CSA and CLSA.
Are wetsuits allowed in races?
World Aquatics and World Triathlon set temperature bands. Below a threshold wetsuits may be required or permitted; above it they are often banned. Always read the event’s rule sheet.
What is sighting?
Lifting the eyes to pick a landmark or buoy without breaking the stroke. It is the skill that replaces the black line.
Is a pool 1,500 m enough preparation?
It is necessary and not sufficient. Currents, chop, cold and navigation only appear outdoors.
The minimum outdoor kit is a bright cap, goggles that handle glare, and a way to be seen. A wetsuit is a temperature and flotation tool with rule bands, not a default.
Tow floats, whistles and thermometers are cheap. They do not replace a chosen exit or a person on shore.
Core kit
- Bright silicone cap — Orange or pink for visibility to boats. Club latex caps tear; carry a spare.
- Tinted or mirrored goggles — Sun on water blinds clear indoor goggles. A second clear pair for overcast days.
- Tow float — A dry-bag buoy on a waist leash. Visibility and a rest handle; not a life-raft.
- Wetsuit (when rules and temperature say so) — Swimming-specific suits have flexible shoulders. Triathlon suits are the common rental.
- Thermometer — A cheap probe prevents “it felt fine” stories after a 12 °C shock.
- Watch with GPS — Useful for mapping a first lake loop; not required for a club out-and-back.
Optional
- Neoprene cap and gloves — For shoulder-season swims. They change stroke feel; test before a race.
- Ear plugs — Cold water in the ear canal can trigger an ice-cream headache or caloric vertigo in some people.
- Grease — Lanolin or similar at seams and chafing points on long Channel-style swims — not a heat strategy by itself.
- Safety whistle — On the tow-float lanyard. Boats hear a whistle better than a shout.
Care
- Rinse the suit — Inland lakes leave algae; seas leave salt. Both rot zippers if left in a trunk.
- Dry the float bladder — A sealed wet float grows a smell that announces itself in a shared car.
- Check the leash clip — A failed waist clip is how a float becomes litter and a swimmer becomes invisible.
- Retire fogged lenses — Anti-fog fails; spit is a field fix, replacement is the plan.
Budget bands
- First lake — Cap, outdoor goggles, tow float. Swim where there is already cover.
- Season regular — Own wetsuit if the local water sits in the suit-legal band most of the year.
- Event bag — GPS watch, spare cap, anti-chafe, and the event’s required kit list.
- Expedition — Escort boat, ratification fees and grease — a Channel budget is not a Saturday 2 km budget.
Outdoor kit is about being seen and staying inside a temperature plan. The expensive expedition layer is optional and rare.
