What Our Runners Say
“Cascade express marathon 2025- This race was a gem. The course had some of the most breathtaking views, quiet, scenic, and fast. Big shoutout to Jess and Sabrina for being super responsive with my pre-race questions. Aid stations were spot-on. Volunteers held blue-striped cups for water, which made it easy to pick. Gatorade was available too, but I appreciated the clarity, no guessing, no fumbling...oh the best part - I am going to Boston because of this marathon” -- Biswanath
