Lakewood, CA — September 12, 2026 — For our 5th year running, Sender One is hosting Summer Send-Off, their biggest celebration of the summer. It’s a full day of climbing, fun challenges, live music, local vendors, food, and drinks, all built around the community that makes our gyms what they are. One last hurrah before school, work, and routine take back over.
This isn’t a competition, it’s a celebration. Get on the wall, send something new, or just show up for the good vibes. Bring your best summer style! Hawaiian shirts, sunglasses, beach vibes… dress it up and earn an extra raffle ticket.
Everyone who participates has a real shot at winning. Attendees earn raffle tickets throughout the day just by trying activities, then drop them into the prize box of their choosing, so a first-timer and a longtime climber walk in with the same odds. For anyone who wants a competitive edge, a handful of activities run live leaderboards all day with a prize for whoever tops each.

- Climbing Challenges — top rope route, boulder problems, pairs bouldering route, climbing with floaties, mantle challenge, bouldering obstacle course, and more
