Entries are open for Active Sunderland's BIG 3 in 1 event in a month's time.
The BIG 3 in 1 is a new event for 2017 and will includes a fun run, bike ride and walk.
Designed for younger people and families, it gives everyone the opportunity to have a go at one, two or all three of the 2017 BIG Event activities in one day.

Sunderland City Council’s Portfolio Holder for Public Health, Wellness and Culture, Councillor John Kelly said: "The Active Sunderland BIG 3 in 1 is a fantastic new event for 2017, designed in the main for children as they can have a go at three events in one afternoon.
"As well as the bike ride, walk and run there is also a fantastic programme of fun family activities for everyone."
As part of the BIG 3 in 1 walk, children can join a new scavenger hunt, a hands-on experience collecting various objects as they go.
