WAUWATOSA, Wis. (CBS 58) -- A lot of people who are close to the work at Children's Wisconsin know and supported Al's Walk -- a decades-long tradition that raised money to support families. 

The final walk was in 2022, but Children's Wisconsin is bringing a new event with the same giving spirit.

"This will be, for those of you who enjoy sports or enjoy pep rallies, the biggest pep rally you've ever attended," said Gil Perry, president and CEO of Children's Wisconsin.

Rally Round will happen Sept. 13 at the Milwaukee Mile. 

A concept video shows a music stage, bounce houses, and tents. Leaders say there will be lots to do for families and the track will be open for people to walk or run on in support of the hospital. 

Registration is open now.
