Well planned and executed event. Many roadblocks in 2020 but the event was successfully moved and executed with professionalism and extreme competence by all Volunteers and staff.

The Big Sipper was a great run. Really enjoyed it. Signage was great and the finish line atmosphere was great too. Definitely do this again next year.
