Bolder Boulder. We had planned it out a month before deciding we we go as a group and have matching hats. We decorated each hat with our own personalized badge.
Since it was a 10K competition (6.2 miles) we each took a mile that we would be the leader for. For an entire mile, the mile leader could tell the others what we would do. Some leaders made people join hands and skip; some had us spin around; I had everyone pose in front of some flowers (they decided on the silly poses).
We were in a walk/jog group so the whole thing took us about 100 minutes and we had a wonderful time enjoying all the musicians and performers along the route. All in all it was a very fun day that I was glad to take part in.
