Great for mountain biking but not your average bike ride.

I was aiming for a 20K trail-running PR today. It’s been raining cats and dogs, pigs, and cows, all week. I wish I had taken that into account more.

Aside from the course being very poorly marked with virtually no blazes or markings, which is why I rate it 3 stars, there is no forewarning that the trail is in a flood area. As far as I know there were no prior flood warnings announced. Perhaps there were in Fairfax County and in Northern Virginia, or perhaps I missed the announcements up here in the Baltimore County area.

Howbeit, this literally turned out to be one of the worst days to run a 20K, period. I ran right into above knee-high flooding when I got to the Difficult Run portion of the course. See my recording — I took a photo of this disaster. I was actually going to continue running through the flood which went on for miles, but the flood height would not relent — knee high and below is probably okay but still a risk, but thigh high is not a good idea at all. One simple cannot see all the under water snakes, rats, and other biting creatures trying to survive after being swept away by flood waters. Also, one runs the risk of being swept away by ensuing rapids. It’s just not a good idea.

I had no choice but to take a detour out of the park altogether onto the closest nearby road. I still managed to get in 10 miles; so at least I got in some weekly mileage.

It was only after I finished that I found out that this trail is in a high-risk flood area, and there was a news announcement 3 days ago. Here’s the web link:

ADVANCED WARNING: If you plan to run this course and it has been raining, do yourself a favor and find out the conditions of the course before launching out. Maybe I’ll return to complete the course, but I will ensure the area is completely dry first. Ugghh!!!

The paths were great but the only thing I didn’t like was that there were no markers or many signs on what path you were on. It’s a maze and it would be great to have more markers/signs. Thank goodness for this app.

Stunning ferns covering the ground make for a nice change in the flora you typically see. Fun for walking, running, and biking.

Lake is small - no spectacular views but it's a nice trail. Lots of roots and rocks to walk over, which I really enjoy but may be problematic for some. Trail gets very narrow in several areas so it's hard to pass. Lots of mountain bikers also use this trail, which can make for some very close calls in the narrower areas.

it's an ok trail. It has campsites and houses stationed at some points. it is rated moderate, but I will call it easy.

Easy to get to with plenty of parking. It is a very small lake, but has a lot of trails that are well maintained. Summers are great with picnic tables and hammocks, but they are removed after summer. Many trails are very narrow making it difficult for bikers and walkers to share.

great trail riding on a mountain bike needs more signs.

Decent walk, nothing difficult and kind of scenic.

This was ok, not much in terms of scenary, albeit it was an early spring day with leaves still on the ground. Trail is good for mountain bikes though, passed quite a few on the way. No trail markers, or at least couldn't see any, and visitor's center wasn't helpful past handing out a map. Once you find the trail though, it's pretty straight forward to follow it. Will likely return with a mountain bike.

Very nice trail that I run 2-3x a week. More mountain bikers than runners though. For every 10 mountain bikers I see, I see one runner. Everyone shares the trail and is very courteous. My Fitbit says I do an elevation of 400 feet or roughly 31 stairs climbed, so reasonable incline work is present on the trail. Many different paths can be chosen to mix up the experience.

Quick easy & nice fall colors.

It's a nice trail for jogging, running, and biking. The circuit I used to run on a regular basis begins near the campgrounds (just NW of the soccer fields), passes alongside the bridge, then the lake, continues through the woods across a small stream, and around the fields. The terrain is relatively flat with a rocky patch near the bridge and a few hills to the East.
