MultiSport
There are two main multisports that have a swimming element:
Aquathon
This sport has 2 components, swimming and running. Typically a standard race is a 750m swim followed immediately by a 5k run; but there are many variations, and youth events are typically much shorter.
Triathalon
A triathalon is similar to an aquathon, but has an additional cycling leg between the swimming and running. The adult sprint triathalon has a 20km cycling leg, but again there are many variations.
Any swimmers interested in taking part in multisports events may find the following links useful:
