Before you go, be sure to check out these running resources.

If you are heading to the local trails during the spring and fall, in particular, be sure to be up to date on the local temporary trail closures which tend to usually include South Boulder trails like Marshall Mesa and Dowdy Draw and in North Boulder, trails like the Eagle trail which tend to get very wet and sticky with mud. Even when they are not closed, remember its a good idea to be prepared to be wet by staying on the trail vs, making the trail wider.

Boulder Open Space and Mountain Parks

Most trails are managed by Boulder's OSMP or Open Space and Mountain Parks. You can find updated trail conditions as well other important stuff in the parks by following their twitter feed @BoulderOSMP.

You can find more about everything on their Visitor Information page.

Running with a Dog

OSMP lands have approximately 145 miles of trails, almost 90 percent of which are open to dogs. It is your responsibility as a dog guardian to read and understand the regulations so that everyone can enjoy their visit to OSMP. In some areas, dogs must be leashed. In other areas, dogs may be allowed off-leash if they wear a voice and sight tag and are under voice and sight control. All dogs must be leashed at the trailheads.

Meyer’s Homestead Trail

The 8.5mi trail loop at Walker Ranch is a local favorite for Mountain Biking and trail running due to its technical and scenic trail and to its proximity to Downtown Boulder.

"Zen and the Art of the Easy Run" - I took it out a bit too fast yesterday. Headed out at a pace that felt comfortable at first then progressively got faster. For all intents and purposes this became what Greg McMillan would call a Fast Finish run. So today I needed to go easy. But going easy can be tough. Read how I got through it.

Marshall Mesa is Muddy

What I always seem to forget is how sticky the trails get along Marshall Mesa Trail, Community Ditch and Dowdy Draw. Its that wonderful soil that just like to build to a nice girth on the bottom of your shoe, making it very awkward to keep a decent stride. I
