FATMUG at Rock the River FXBG

Come visit FATMUG at the 2015 Rock the River FXBG on Saturday June 6 at Old Mill Park in Fredericksburg! We’re excited to announce that we’ll be on hand all day to promote our cause AND offer several activities for those interested in Mountain Biking! Be sure to come out for the first event of its kind in Fredericksburg, and be sure to stop by and see what FATMUG has to offer! Check out for full details of the day’s events!

Bike Maintenance Clinic

Interested in learning basic bike maintenance techniques from the professionals? Staff from Fredericksburg's Olde Towne Bicycles will be on hand to offer basic bike maintenance clinics. These offerings will be free of charge and details including topics and times will soon follow. Check back here often for specifics, as we will post them once they’re available!

Bike Parts Swap

Do you have extra bicycle parts just laying around collecting dust? Why not give them a second life, all while putting a little cash back in your pocket! Bring your old cycling items with you to “Rock the River” Saturday June 6th at Old Mill Park in downtown Fredericksburg. FATMUG will be hosting several activities throughout the day, one of which will be a community bicycle and parts exchange.

FATMUG will provide the space and staff to facilitate this event. All you need to do is drop off the items you’d like to sell at the beginning of the event, let us know your bottom line price and we’ll do the rest. Simply come back at the end of the day to collect your cash! Although you’ll probably want to stick around to find great deals on items you might be looking for yourself! And of course you won’t want to miss any of the fun activities, numerous vendors and workshops, delicious brews and great music at Fredericksburg’s first annual Rock the River. Please consider coming out to support a great community organization at a great community event!


1. Do I need to register? Just drop us an email or give us a call so we’ll know what you’re planning on bringing. This helps us plan space accordingly.

2. Does it cost money to participate in the swap? For this year’s event FATMUG will collect a 25% commission on all parts sold at the swap. Of course you’re more than welcome to donate more than the standard 25%. What’s good? The money goes exclusively to FATMUG, a 501c3 non-profit organization, so it’s all completely TAX DEDUCTIBLE! We’ll even give you a receipt! What’s better? FATMUG uses these funds to help build new, and maintain existing, mountain bike trails at the Fredericksburg Quarry and Mott’s Run Reservoir! The riding here has never been better!

3. Don’t have any parts to sell but still want to help make this event a huge success? We always welcome volunteers! Just give us a call or email and we’ll let you know what we need help with.

Motts Run Mtb & Quarry Trails Are Open.

The trails are in great condition.   Thanks and happy riding!


Also, a friendly reminder that Motts Run closes at 7pm when open (April-October; closed Tues/Wed).


Park users may park outside the gate if they think they may not make it back by closing time. However there is limited space so please carpool if possible. Periodically Motts Run may close early due to inclement weather,  so please keep this in mind.

Thanks for your cooperation.

We are extremely pleased to announce the City of Fredericksburg has approved our proposal to build an approximate twelve mile, stacked-loop, mountain bike specific, trail system on the land around the Motts Run Reservoir! We have begun construction and we will be starting on the second Saturday of every month to hold a larger trail workday/event for any volunteers that want to come. We will have food, drinks, music provided :) For any other trail work days of course see the event calendar below.










We were contacted in early September by an engineering firm who is working with VDOT to conduct an environmental assessment of potential impacts to social and environmental factors that may occur as a result of proposed improvements to the Interstate 95 corridor in the Fredericksburg area.  See the following map and letter for background.  Hopefully by letting VDOT know where our trails are and how much we value them, the trails will be spared during future construction/expansion of roadways. Thanks to Rob Maple for helping send these folks trail location data.

Grading work and storm water run-off control work on the old quarry road is now complete.  We offer a huge thank you to the City's Public Works department for taking care of this!  The improvements they made should eliminate the large volume of fast-flowing water down the road which was eating away at the upstream end of Scout trail.  Past damage is significant in that area but we're hopeful it stays in the past.  You may also notice that many of the orange clay mud-slick puddles under the 95 overpass area are vastly improved from this project.  Thanks again Public Works!


Andrew Thorpe created this detailed "Courtland Trails" Booklet. So if you run, bike walk the trails near Courtland or just a little curious about it please check it out.  Courtland Booklet


1. Maintain the integrity of existing trails.

2. Identify areas for improvement on existing trails and execute sound practices to reduce impact on surrounding environment.

3. Design and construct trails to minimize both risk of user harm and environmental impact from all reasonably anticipated trail use for life of trail.

4. Solicit guidance from local historians to design, construct and/or modify trails that provide low impact access to cultural and historical features and landmarks.

5. Repair trail damage resulting from severe weather events, fallen trees, debris and improper trail use (ex. muddy surface riding, unauthorized re-routes, etc.).

6. Educate trail users, especially cyclists, on proper trail use etiquette.
