Some Hannibal residents boosted their cardio while supporting a good cause on Saturday.
It was the
3rd annual Shine A Light on Autism Lighthouse Challenge in Hannibal.
About 200 runners and walkers took part in the event.
There were three categories that runners could choose from.
Money raised from the event went to autism awareness.
Runners went up the 244 stairs that started from the base of Cardiff Hill and went to the top by the lighthouse.
Some of the runners made several laps from the bottom to the top and back down.
