Ran this trail from RaceTrack Road Endpoint. There is a parking lot, right at the start of the trail. The trail is 5.5 miles, total. It is apparently at the end of the 5.5 miles, and heads towards Glendale/Lanham. The trail appears to be between neighborhoods, and you cross over a few bridges, following power lines. It is best to go right when it starts to get light out, in the summer, as I can imagine, it will be too dark before. Also, mid-day, it may be too hot, although the trail in some spots is shady. It is decent to run, nice and flat, not much to see but very peaceful.

It was nice to share the trail for a 12mile run with many cyclists.Not many runners or walkers.It was a beautiful trail & well kept. I will definitely revisit again.

Pros: Quiet Clean Well maintained Gentle hills Wooded scenery Cons: One Porto potty on trail not much tree shade on trail itself

Pros: Clean Well maintained Easy hills Runs Mainly through forest Some benches through trail Cons: Not too much tree coverage so the sun beats down One porter potty on trail

Too many bumps, gravels and turns. Uneven concrete. I have a very light road bike and it was too much for my gears and pedals

I parked at the York Heritage Rail Trail NE Extension Rt30 Parking Lot to go biking. From there you can walk or bike north and go on a very pretty, well maintained loop for about 5 miles (bathrooms at the park at the end.). If that’s enough for you, it’s a great Trailhead. I rode that north section, then came back and went south from my start point. The first part is a very open section that runs along the creek and has cool views of the city skyline. This then takes you into York city and you must go through some sketchy neighborhoods for a mile or two. After that, you are back in the trail; it runs along the actual rail and it’s wooded and quiet. I saw a deer lazily wandering across the track. If it wasn’t for the couple of miles that made me nervous, I’d give this 5 stars. I will go again but park south of York.

This was a beautiful easy walk. Shady the whole way. Not too much traffic. Parking was not a problem at 10am.

Although I know this part of Montgomery County pretty well (I live about 10 miles away but rarely ride in this direction), this morning I rode the Carl Henn Millenium Trail for the first time. It is much as I expected from having driven around through this area many times. The section west of I-270 is more pleasant and the entire trail is characterized by some gentle long hills that wind along some fairly busy roads as well as some quieter more forested areas & some sections with homes. I started at the Fallsgrove Stream Valley Park and proceeded east, which means that I was riding clockwise. This is the way to go if you wish to avoid going uphill because in this direction its almost all flat or slightly downhill. The path is well marked & generally in very good shape. All told I enjoyed a pleasant hour riding this almost 11 mile trail.

This is my favorite trail for distance cycling. I drive 40-45 mins here from MD for the quality of surface and the lack of stress in dodging cars on roads. Too bad the C&O Trust in MD is unwilling and/or unable to pave and model their trail after the W&OD. Just beware of oblivious pedestrians with headphones. Pedestrian traffic is higher on weekends and east of Sterling based on trail proximity to towns and residential areas. Otherwise, get out and enjoy!
