It's also a great reminder that Wilson Creek is one of the Treasure Valley's go-to spots for winter riding. The trails there are generally accessible when other areas aren't, so it's a good place to keep your OFT miles going. The challenge wraps up on October 30: https://swimba.org/oft.

A few reminders to keep the trails in good shape and welcoming for everyone:

🟤 Skip muddy, wet trails. Riding them leaves ruts and damages the trail for everyone. If your tires are picking up mud or leaving deep tracks, turn around or pick a drier route.
🅿️ Parking: Use designated parking and leave room for trailers. Please park perpendicular to the outer edge of the lot.
🐴 Share with equestrians: Horses always have the right of way. Slow down, stop if needed, say hello so they know you're a person, and ask how they'd like to pass.

Good trail manners are how we keep access open, and they're part of what SWIMBA works for every day.

See you out there!

Last group ride of the year is this Thursday. 🍂🚵

📅 Thursday, October 15 @ 6 PM
📍 Highlands Hollow Brewhouse

We’re really excited to be teaming up with the Shifty 150, a women’s October riding challenge, for this one! They’ll be meeting us at the Hollow before heading out on their own women’s ride. We’re encouraging our members to join the Shifty crew, so come say hi and see what it’s all about.

Ours is no-drop. We’re planning Red Cliffs, Crestline, Lower Hulls, Chickadee Ridge, and the 15th St. Connector, and if the group’s feeling it, we might add Shane’s too.

It gets dark early now, so consider bringing a light or two. 💡

Then everyone is meeting back at the Hollow after the ride. SWIMBA members get a buy one, get one b**r. 🍻

Thanks to our ride sponsors, Club Ride Apparel and Highlands Hollow Brewhouse, for supporting the group rides this year. 💚

RSVP with the link below. See you Thursday!

What a morning on the Boise trails. Fall weather was here today! Huge thanks to Braydon Bringhurst for leading an intimate group ride today — the perfect mix of fall colors, cool air, and good conversation.

There’s something special about sharing an autumn morning with riders who show up ready to connect and enjoy the moment. Braydon brought his signature positivity and trail wisdom, and the group made it feel personal in the best way.

We are grateful for everyone who joined us and helped make this fall ride one to remember.

What an incredible night at the Valnova's Kirkhills Bike Park Grand Opening in Eagle on Tuesday night. Huge congratulations to Valnova and deep appreciation to Braydon Bringhurst for launching a world‑class riding spot right here in the Treasure Valley. The event included a ribbon cutting, racing, and a community turnout that showed just how strong MTB culture is in Idaho.

SWIMBA was proud to be there, supporting the event and connecting with riders of all ages. We also want to thank everyone who entered the raffle that night, which included a Thule Verse 2 hitch rack! Your participation helped raise funds that go directly toward SWIMBA’s mission to build and maintain trails, protect access, and grow mountain biking across the region.

The energy, the racing, the giveaways — it all made for an unforgettable opening day.

A big thank‑you to Bikes & Beans for their generous support of SWIMBA’s OFT Challenge.

Bikes & Beans is one of Boise’s most community‑driven bike shops — a place where riders can grab a coffee, get expert service, and connect with people who genuinely care about the local cycling scene. Their commitment to supporting riders and trails shows in everything they do.

We’re grateful for their partnership and for the positive impact they continue to make in Boise’s MTB community.

A huge thank‑you to 28th Street Barre for stepping up as the Title Sponsor of SWIMBA’s OFT Challenge.

Their support goes directly toward SWIMBA’s mission — building and maintaining trails, expanding access, and strengthening mountain biking across the Treasure Valley.

28th Street Barre is a locally owned Boise studio offering barre, dance, MELT, Pound, Pilates, and radical rebounding in a warm, community‑driven space. Their commitment to movement, wellness, and connection aligns beautifully with the spirit of mountain biking and the OFT Challenge.

We’re grateful for their partnership and for investing in the future of Boise’s MTB community.
If you haven’t checked them out yet, give their studio a look — they’re an awesome part of the north‑end community.

Thank you, 28th Street Barre , for helping keep Boise’s trails thriving.

The Kevin Pavlis trail network in Avimor has been riding great, but late‑summer growth is starting to creep in — and we could use some volunteer help to keep the corridors clear.

We’re hosting a trail work party this Saturday (9/12, 9:30AM - 1:30PM) to cut back encroaching vegetation, to do a bit of tread work, and to make sure the trail network stays fast, safe, and fun heading into fall. This is an easy way to give back and help keep them in top shape.

Bring gloves and water. All skill levels welcome.

We’re back on the trails — and yes, it’s going to be a hot one! The forecast says dry and dusty, but that’s part of the adventure. Join us Thursday, August 20th, 6 PM, departing from, and returning to, Highlands Hollow Brewhouse.
