Peterhead Swimming Pool will host a Children & Family Aquathon tonight as part of an Aberdeenshire Council run series.
The Aquathon is a swim-then-run event where children aged from eight to sixteen can take part as individuals or as a team with an adult.
The swim section of the competition will be between 50 metres and 400 metres depending on the age of the participant.
The running stage will range from 600 metres to 3 kilometres, also age dependent.
Registration for the event opens at 6pm at Peterhead Swimming Pool for a 7pm start.
Participants can also register in advance at www.aberdeenshire.gov.uk/recreation/events
