Visit the Wahl mobile barber shop this weekend and get your beard trimmed for a good cause. $1 from every free haircut will benefit ZERO—The End of Prostate Cancer, a nonprofit working to fight the most commonly diagnosed cancer in men. Bonus: the visitor with the most striking facial hair will be named the 2015 Wahl Man of Denver. Friday through Monday, 10:30 a.m. to 8 p.m.; Denver’s Civic Center Park

Saturday and Sunday, 10 a.m. to 7 p.m.; Boulder County Fairgrounds, 9595 Nelson Rd., Longmont
Nan Desu Kan Charity Auction & Poker Tournament: This annual three-day convention is primarily a celebration of fictional characters—but that doesn’t stop these anime fans from making a big impact on the lives of real animals. After visiting panels of famous Japanese voice actors and browsing a gallery of fan art, attendees can join in a poker tournament benefitting the Dumb Friends League, a Denver shelter that never euthanizes healthy animals. On-site registration for convention day passes and weekend passes are available at the door. Poker: Friday and Saturday, 10 p.m. to midnight; Auction: Sunday, 4 to 6 p.m.; Sheraton Denver Downtown, 1550 Court Pl.
Colorado Runner Labor Day Mini Marathon: If you’re itching to hit the pavement again before summer ends, this is your chance. Participants have the choice between a half marathon, 10K, or 5K on this flat and scenic track along Cherry Creek. If you’re not in the mood to break a sweat, volunteer to help out with registration or at an aid station and get an event T-shirt, plus free entry into a future Colorado Runner event. After the races, both runners and volunteers can enjoy Naked Juice smoothies and free (and locally produced) Noosa Yoghurt or check out vendors such as Koko Fit Club, RNK Running Store, and Arbonne. Monday, 6 a.m. to noon; Salisbury Park, 11920 N. Motsenbocker Rd., Parker
