Nice words from 2024 runner Dale: Its important to me to thank the people who help make Tucson the awesome community it is! Saturdays Earth Day was fabulous! Ive been fortunate to attend all the races youve had out there! Just the view and space is incredible and what a gift to be able to struggle up the hills while taking it all in! Thank you so much for all you and your staff/team do.

Nice words from 2024 runner Louise: Wow!! Are you guys efficient or what? Thanks so much for the quick turnaround with results and, again, for organizing and running a great event. The water stop was especially appreciated on a hot day. (And even if we were running short of time, the announcer was funny and added an enjoyable element to announcing the winners.)
