Hey there Ravenwolf
I did the 5k Color run and that was a walk/run event as well. For ours they had the left side of the course dedicated to runners and the right side dedicated to walkers
If you ran, you still had to do a lot of weaving because sometimes runners would stop and start walking. But it was fun! Runners and walkers started together in big waves of people
Then you just broke off into your "side" of the track. It was enjoyable but I found it sometimes hard to keep my momentum when someone would stop in front of me and I had to try to avoid them
! I think you'll have fun and it's definitely something you should try at least once!
