We do allow you to roll down to a shorter distance at most of our events, we don't currently allow transfers from one event to another. For example, if you're signed up for the Glen Arbor Solstice Half Marathon, but want to roll down to the 5K, that's cool.  However, if you're signed up for the Glen Arbor Solstice Half Marathon and want to transfer to the Sleeping Bear Half Marathon, that's not allowed.
