$7490 raised for MTB Trail Grooming Equipment

Thanks to all the work put in by Dave Halloway, we raised $7490 for fat bike grooming in Rochester! And we're the top 45NRTH fund raiser!!! That means we have won an additional $3000 to fund the grooming equipment and trailer. Thank you to everyone!

Grant for MTB Trail Grooming Equipment

As a follow up to the article below on getting equipment to groom the mountain bike trails in Gamehaven and Eastwood. Dave Halloway has submitted a $3000 grant request to 45NRTH (that is a company that makes awesome winter bike boots) to help fund a groomer for these trails. To get the $3,000 grant from 45NRTH we have to raise more money than 5 other clubs before January 11th. So far (1/2/2016), $1600 has been raised. Please consider a donation prior to the deadline of January 11. 

Gamehaven Mountain Bike Trail Update (Dec 2015)

Winter Riding

As we look ahead to the winter season and winter fat-biking and with the new Gamehaven trail additions we have around 7 miles of trail which could be groomed. This is a large amount to do without mechanical aid. We are looking into some sort of grooming system. One alternate is an older snowmobile with a narrower stance than modern sleds have - something like an early 80's arctic cat or along those lines. A small children's 120 cc sled might work as well. We would just like to see if it works before purchasing. If you have one or know of one for sale please contact Matt Kurke at

With outstanding fall weather, our mountain bike trail crew has completed another challenging loop. Most recently we have added a connector section that will allow us to make a long loop with the new trail going around the “south” point. This is a scenic ride along the lake with a challenging climb at the end. Temporarily, we will use the Scout road (in red) that will take the riders to the “Rolling Thunder” campsite. Proceed through the campsite to the trail connector and have a fast downhill ride to the trail below. Trail markers – black arrows on a yellow background have been placed to guide you. Please refer to the map below. Many thanks to all who have worked hard on weekdays and Saturday mornings to make this happen. The temporary trail will be replaced with a trail that will run through the woods behind the scout camp sites. This section has been rough cleared and will be ready for grading in the spring.Gamehaven now has close to 7 miles of trail.

Mitchell Trantow, and his volunteers completed the final shaping on the trail running along the lake. His team worked two weekend to complete the task. This is Mitchell’s Eagle Scout project.

High School Mountain Bike Race

Sunday, October 7, 2015

Gamehaven Park, Rochester, MN

One of the five Minnesota High School mountain bike races will take place at the Gamehaven Scout Reservation on this coming Sunday - October 4. We are expecting close to 700 riders from schools around Minnesota and western Wisconsin. Come out and enjoy great competition and cheer for your Rochester Team.

Here is a map of the race course and viewing points marked as green dots.

Root River Park What sort of park do you want?

Olmsted County has begun the process of developing a third Regional Park (Oxbox and Chester Woods are the current county parks) in an effort to respond to the outdoor recreational needs of future generations. In 2007 the Olmsted County and the Minnesota DNR secured approximately 125 acres in Southeastern Olmsted County. Located along the banks of the Root River, this land adjoins roughly 265 acres of DNR-Forestry Land, which lies on the opposite shore. The long-term goal is that these 2 areas be joined to increase the total public land available for nature based, outdoor recreational use. We have been asked for input as to the potential uses of this Root River Park. Some obvious uses are hiking and mountain biking. The Olmsted Co meets on August 19th – so if you have any thoughts on what activities you would like to see developed in this new park, please let me ( know by the 17th. Here is a detailed description of the park

Trantow Leads Gamehaven Trail Project

Richard Trantow and his Scout Team from Scout Troop 498 built a long section of mountain bike trail at the Gamehaven Reservoir. This project was part of his Eagle Scout requirements. The section they worked on was two tenths of a mile of difficult side slope construction on City property leading to the reservoir. Using the IMBA trail manual, Richard learned how to make bench cuts and then taught his team the technique and how to use the trail tools. They logged over 70 hours in completing the project. RASC appreciates Richard’s contribution to the Gamehaven trails which are now being used by many riders in the community.

Boy Scouts with attitude!
