Swimming events can be held in pools or open water. Races might be single‑distance swims, multi‑lap efforts, or relays where teammates share the distance.

Typical distances range from 500 m and 1 km “intro” swims up to 5 km and 10 km marathon swims. Pool events often follow lap‑based formats with time limits.

In India, open‑water events are growing in lakes, reservoirs, and along the coastline, while pool meets continue in city clubs and academies through the year.

New swimmers focus on relaxed technique, sighting, and comfort in different water conditions. Choosing a wetsuit‑legal or warm‑water event can make first races less scary.
