It's an event where participants will climb 75 flight of stairs to the top of the tallest building in Texas, Chase Tower, Downtown.
It all benefits Alex's Lemonade Stand, a foundation that's fighting childhood cancer one step at a time.
We caught up with one of the event's ambassador families.
The Lemon Climb will take place on March 24 from 8:30 a.m. until 11:00 a.m.
