Race Info
The Tucson Shamrock 10K is an out-and-back run on the paved Rillito River Loop trail system, starting and finishing at Brandi Fenton Memorial Park in Tucson. The route stays on dedicated asphalt and concrete trail and is nearly flat, with only a few meters of elevation change. It shares its start and finish line with the half marathon and 5K on the Sunday of the St. Patrick's-themed race weekend.
