On Sunday September 1 at Horfield Leisure Centre, Bristol, Thistle Hotels and Lite@Nite are holding a children's Triathlon.
The event is open for children between 6-12 years old and there will be a swim, bike ride and run/walk for any kids who want to take part, regardless of ability.
There will also be a number of other fun events and attractions, including bouncy castles and all children who enter will receive a branded running top, finisher's medal and a branded bag as well as drinks and snacks.
There are also four other similar events: 3 August in Glasgow, 10 August in Newcastle, 18 August in Manchester and 31 August in Birmingham.
Check out the charity at www.liteatnite.co.uk and you can find the flyer for the Bristol event here.
They are also looking for volunteers to help out with the events, so if you'd like to help out, get in touch.
