This in a nutshell is not an easy course! You can take your best road half marathon time and add 20-30 minutes. Parts of the course are rocky, rooty, and certainly hilly. The final course map is yet to be determined, but it will be a two loop course utilizing many different types of trails in the park. Total amount of elevation will be close to 3K.
