Keep On Movin' Soul ll Soul
It's to raise money for Cancer Research UK.
Most of us have heard of Race for Life - but this year you and your friends can Relay for Life as well!
The 24 hour event is taking place at Yate Outdoor Sports Centre on Saturday 3rd - Sunday 4th July.
On that weekend teams will gather at the sports centre and from midday on Saturday they will try and keep at least one member of their team on the running track at any one time for 24 hours until midday on the Sunday. They can run, jog, skip or just walk!
Teams camp in the middle of the track overnight. In the meantime there's loads going on including live music, kids entertainment (including a play bus and bouncy castle) as well a hog roast and much more.
Organiser Tina Nolan has told Heart its open to everyone: "All ages, all physical abilities...everyone is up there for the same thing to raise money and awareness for Cancer Research UK. Everyone just has a really fabulous time so it doesn't matter who you are, how old you are or where you are from - you are very welcome to come and join us."
