Adult Beginner Mountain Bike Class, July 1st and 8th.

13346381_10153546555780906_6112802910764469529_oWant to keep up with your kiddos on the singletrack trails?

Looking to move from the paved bike path to the new trails that twist and roll through the woods?

Join us for two Monday evenings July 1st and 8th from 7-8:30pm at Mirror Lake Park to cover the basics and get you out on the trails!

We will cover bike checks, shifting and braking effectively, riding up and down hills, and turning/cornering.

We focus a lot on separating yourself from your seat so you can use the whole bike to balance through varied terrain.

Our curriculum is based on the NICA high-school inspried program used in our CMBR kids classes.

This class is for 18+. Priority is given to parents with children registered in the CMBR kids program.

Midsummer Masher Race, June 30th. Registration Open!

Midsummermasher logo[12864]


The Mirror Lake Midsummer Masher mountain bike race is offered in partnership with Arctic MTB’s summer Mountain Bike series.  Arctic MTB (through the Arctic Bicycle Club) covers the insurance and registration for the Midsummer Masher as well as the vast majority of Southcentral Alaska’s summer bike races (Road, Mountain and Cyclocross.)  A portion of every Masher registration is donated to CMBR.

WHEN: Sunday June 30th, 1pm start.

WHERE: Click for the Midsummer Masher Map on Trailforks

COST: early registration is $20 adults/free for juniors ($30 race day). An annual Arctic MTB (ABC) race membership is required.  This is not the same as a CMBR membership.  For those racing the Arctic MTB series, please bring your bib, but you must register for the Midsummer Masher separately.  ArcticMTB will donate $5 from each registration to CMBR. (Registration is $30 day of race.)

Wilson’s Way

Chris Wilson is the guy who started the Mirror Lake Singletrack project. He and a small crew of volunteers worked for years pushing the idea, raising funds, designing trails and building community support. We’re happy to name the Yellow Trail WILSON’S WAY after Chris.

Announcing Maeve’s Maze!

We’re stoked to announce that Maeve’s Maze is one of our newly approved trail names!

Maeve’s Maze is a part of the new session loops in the purple section, filled with nice flowy berms and a few good jumps. It’s also pretty easy to get turned around in there if you’re not paying attention!

Maeve is a Senior Park Planner for Anchorage’s Parks and Rec and has spent years pushing our projects to completion. Thanks, Maeve for all you do to strengthen mountain biking in our communities!

Thanks, Maeve!

Come out to Matanuska Brewing in Eagle River this Sunday February 10th 6:30pm and help us pick some real trail names for the Mirror Lake Singletrack!

Yep, the colors were always meant as a temporary thing. Our Grand Opening is June 1st, and we need to get our maps and signs ready.

We’ll be drinking beers and brainstorming upstairs, so please stop by!

4. Renew your CMBR membership today!

Thanks to everyone who renewed their memberships during our winter fundraising drive!  Upcoming trail projects include maps and trail signs, repairing muddy spots, adding a few skill-building features and year-round trail mainentance.  Our youth summer program CMBR-kids will be starting up in June and spring trail work starts mid-May.  If you haven’t already, please consider joining or renewing your CMBR membership!

5. Thanks trail packers and groomers!  WE LOVE SNOWSHOERS!

We’re lucky to have a crew of folks who regularly snowshoe the trails to pack them down for fat bike riding, this helps smooth out any bumps left by walkers..  Please tell your friends that we welcome snowshoes on the trails!
