The Southwest Idaho Mountain Bike Association (SWIMBA) is a 100% non-profit, volunteer organization dedicated to building and preserving a world-class, multi-use trail network in Southwest Idaho.

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.

Ride easy, hydrate well, and afterward, cool off with friends — SWIMBA Members get buy‑one‑get‑one beers, and 10% of all Highlands Hollow sales go straight to supporting the trails we love. Even when the temps rise, we keep rolling. See you Thursday!

SWIMBA Position on Proposed Eagle Fire District Maintenance & Training Facility (CUP‑2026‑13)

SWIMBA appreciates the opportunity to comment on the proposed Conditional Use Permit for the Eagle Fire District and City of Eagle facility at 11280 N. Horseshoe Bend Road.

SWIMBA fully supports the critical role our first responders play in protecting the open spaces we all enjoy. We are not opposed to the Fire District’s need for a maintenance and training facility. Public safety infrastructure matters — and we value it.

However, we believe this specific location poses a significant impact to existing recreational opportunities at the Ada/Eagle Bike Park and surrounding open‑space areas. Even with planned trail connectivity, the size, scale, and operational demands of the proposed facility would introduce noise, lighting, traffic, and activity levels that fundamentally change the character of this recreation hub.

Eagle has spent years building a community identity centered on trails, parks, pathways, and open space. These amenities are a major reason people choose to live and recreate here. Protecting them should remain a top priority.

SWIMBA respectfully requests the Commission deny the application as proposed and evaluation of alternative sites that meet public safety needs without sacrificing recreation, trail connectivity, or open‑space values.

If the application continues forward, we urge the City to closely evaluate:
• Impacts to current and future recreational activities
• Trail and pathway connectivity
• Noise, lighting, traffic, and operational effects
• Opportunities to preserve or enhance recreation as part of any City benefit
• Alternative locations that better balance safety and long‑term recreation access

SWIMBA’s mission is to create, protect, and sustain a world‑class multi‑use trail network for all. As growth accelerates, preserving Eagle’s remaining open spaces becomes even more important.

We ask the Commission to prioritize recreation, public access, and open‑space preservation when evaluating CUP‑2026‑13 — and require clear justification that this site is truly the best and most compatible location for the proposed facility.

The meeting will take place on Monday August 3, 2026 6:00PM at Eagle City Hall.

🔥 SWIMBA July Group Ride Update 🔥

Due to the forecasted ~100° temperatures and the current Ridge to Rivers trail closures related to the Claremont Fire, we’ve made the decision to cancel this Thursday’s group ride.

BUT we’re still getting together!

Join us Thursday, July 16, from 6:00–8:00 PM at Highlands Hollow Brewhouse for a relaxed social evening with fellow riders. Grab a burger, enjoy a cold drink, catch up with friends, and meet new members of the SWIMBA community.

As always, SWIMBA members get buy-one-get-one beers, and 10% of all Highlands Hollow sales for the day will be donated to SWIMBA, helping us continue to create, protect, and sustain the trails we all enjoy.

We know we’ll all be back on the trails soon. Until then, come raise a glass with us—we’d love to see you there!

We want to extent a massive thank-you to everyone who supported the Boise Mountain Bike Festival this year — from the Braydon Bringhurst-sponsored sweepstakes contributors to the day‑of raffle participants. Because of you, SWIMBA raised over $7,000 in net proceeds to keep building and advocating for mountain biking and building and maintaining trails in, and around, Southwest Idaho.

Saturday’s weather at Bogus was cold, wet, and a little wild, but the community still showed up strong. Riders rode, families explored sponsor booths, and everyone came together to celebrate how far mountain biking has come in the Treasure Valley.

Your support — whether you bought a sweepstakes ticket, grabbed a raffle entry, volunteered, or simply showed up in the rain — makes a real impact. The growth we’re seeing is because of this community.

Thank you for helping make the festival a success. We’re already excited for next year.

Get ready, folks. Idaho’s Galena Grinder is coming up on July 18th. It's one of the best MTB races in the state, and the perfect excuse to escape to the high country. Fast singletrack, big views, cool temps, and that classic Galena vibe that makes the whole day feel like summer should.

Whether you’re racing for the podium or just want to test your legs on some of Idaho’s most scenic trails, this is the one you don’t want to miss.

Get signed up, get tuned up, and we’ll see you at the start line.

Summer is here, and we're riding. ☀️🚵

Join us for the 3rd Thursday Group Ride this Thursday — one of our favorite traditions of the season, and last month's turnout was a reminder of why we keep showing up.

📅 Thursday, June 19
⏰ 6:00 PM
📍 Highlands Hollow BrewHouse

Come ready to roll — it's going to be a hot one, so bring plenty of water and sun protection. All paces welcome. No-drop. Good people. Cold beer at The Hollow after.

A big thank you to our sponsors making this ride possible: Highlands Hollow Brewhouse and Club Ride Apparel — whose gear you might already be eyeing in the Boise Mountain Bike Festival sweepstakes.

Speaking of which: entries close this Saturday, June 20. Every entry supports SWIMBA, Crank Queens, and Idaho Women's Bikepacking, and with 8 prize packs up for grabs, the odds are genuinely good. Events like Thursday's group ride exist because of this kind of community support.

🚵🏻 RSVP for the ride: https://swimba.org/events/2026-swimba-group-ride-2/

A few spots are still available for this Wednesday's MTB Fundamentals clinic at Eagle Bike Park — and we didn't want any members to miss out. 🚵

📅 Wednesday, June 17 — 6:00–8:00 PM
📍 Eagle Bike Park | Free for SWIMBA members

Register here: https://swimba.org/events/mtb-fundamentals-skills-clinic-members-only-6/

Coach Levi Weert covers body position, balance, speed control, and movement on technical terrain using a structured drill format that's easy to keep practicing on your own. These are the kinds of skills that make every ride feel a little more dialed — and this is one of only a handful of clinics we offer throughout the season.

This is what a SWIMBA membership looks like in practice. Free clinics, community rides, and access to the events and resources that make riding in Southwest Idaho as good as it is. None of it happens without the support of members and donors who believe in building something worth riding for.

We've got more clinics coming later this summer — the best way to stay in the loop is to join our email list at swimba.org.

And if you haven't entered the For the Ride sweepstakes yet, you've got 5 days left. Every entry goes directly back to SWIMBA, Crank Queens, and Idaho Women's Bikepacking — the kind of support that keeps clinics like this free.

Sweepstakes: https://swimba.org/2026-mtb-festival-sweepstakes

Members: log into your account and head to the Events section at swimba.org to register for Wednesday.

The Boise Mountain Bike Festival is June 25–27 — and the event needs volunteers to help make it happen! 🙌

We're looking for help at two venues:

📍 Friday, June 26 — Eagle Bike Park
📍 Saturday, June 27 — Bogus Basin

Shifts are available for setup, registration, and tear down. All volunteers will receive a lift ticket, festival access, and event-themed swag as a thank-you for helping out.

If you've got a couple hours to give, email info[at]swimba.org with which day(s) and shift type work for you and we'll get you the details.

The Boise Mountain Bike Festival is a community event and a fundraiser for SWIMBA, Crank Queens, and Idaho Women's Bikepacking — three local organizations working to build more trails and get more people on bikes across Southwest Idaho. As part of the event, we're running the Boise Mountain Bike Festival Sweepstakes, with prizes including a Canyon Spectral 8 and gear from some great brands. Every entry goes directly toward that mission.

Not entered yet? Find the link on our website at https://swimba.org/2026-mtb-festival-sweepstakes. And if you know someone who'd want in, share it with them.

Thanks in advance — this event is a community effort in every sense.
