My husband and I have done serveral races that are a part of the GCM and each one is incredibly organized and well done. This year I did my 1st half marathon at the GCM and it could not have been a better experience. The course was perfect and the finish at the Glass Bowl was really neat. The volunteers were great and there were so many of them. Mile markers were well done & it was nice to have times and splits called out during the race
