I had a really fun time hiking with the family in Patapsco Valley State Park yesterday. We hiked west from Henryton Rd. on the through trail, for a total out-and-back distance of about 4 miles. I had only hiked here once before, back in 2014. It’s a very nice, less busy area of the park just east of Sykesville. We found several caches along the way, climbed a few trees, and Andrew got to do some bouldering with his new crash pad. I keep telling myself that one of these days, I’d like to through-hike the entire park from Halethorpe to Sykesville. If planned correctly, it could probably be done as a 1- or 2-night backpacking trip.

This morning, I had planned to ride my mountain bike, which I haven’t done since early December. The predicted low was 24°, but once again, the actual temperature ended up hovering within 1 or 2 degrees of freezing, so I bagged it and took a road ride instead. When I actually got outside, it seemed colder than my weather app had indicated, and I suspect the trails probably would have been OK. I saw a lot of people in the park, including several groups of mountain bikers, which is unusual for a weekday morning. I suspect things will return to normal next week, when most people will be back at work. I’m really hoping that January will bring some colder mornings that will solidly freeze the trails. In the meantime, I’m going to either have to put up with mud, or hit the pavement instead, as I did today. I ended up going about 24 miles and looping through UMBC. Not a bad ride, even if it wasn’t what I had planned.

Last year was my first-ever experience with mountain biking in the winter. Back in the ’90s, I was a casual, weekend-only, warm-weather mountain biker. Nowadays, in Patapsco Valley State Park, it’s all about avoiding the crowds. That means riding on weekdays, usually in the morning, and often in the cold.

One of the first things I learned about mountain biking in the winter is that I stay warmer on the trails than I do on roads. My first few times out, I dressed essentially the same way I do for cold road rides, and found myself getting hot and sweaty. I’m not sure why this is, but it probably has something to do with the slower speeds involved, as well as the tree canopy and terrain, all of which combine to reduce wind chill. Mountain biking is also more like interval training than road biking. There are short stretches of heavy exertion, alternated with downhill bursts, and occasional dismounting to get around obstacles. On top of that, you have to move around on the bike a lot more to keep a stable center of gravity through technical sections. All in all, it’s a much more dynamic activity than road biking, and involves a lot more muscle groups (particularly the core muscles). The upshot of all this is that I’ve learned to dress somewhat lighter than I do when I hit the roads. Of course, the only problem there is that whenever I do hit a short stretch of pavement, I get cold really fast. I try to minimize riding on pavement when on the mountain bike, but a certain amount of it is unavoidable.

The other thing I learned about is the strange phenomenon known as the “freeze thaw cycle” that affects the trails during the colder months. Overnight and in the morning, the trails are frozen, which makes for fantastic riding conditions. However, once the sun warms the ground above freezing, all of the moisture thaws out, and the trails turn into a muddy mess. This was a constant problem when I was commuting by MTB. The morning commutes would be total frozen awesomeness, but my afternoon rides would be mud baths. There were a lot of days where I rode home on roads, in the interest of staying off the trails. Of course, with my current work-from-home situation, this is not really a problem — I just stick to riding in the mornings.

We’re just now starting to get into the freeze-thaw cycle for the winter of 2020-2021. This morning, with the temperatures hovering right around freezing, the exposed trails were frozen, but the trails deeper in the woods were still thawed and a bit soupy in places. Trail conditions have been less than ideal lately because of our extremely wet fall weather, so I’m counting the days ’til the overnight temperatures fall down to the low-to-mid 20s, which will freeze everything up really nicely for my morning rides.

I bought my first mountain bike in 1994. Actually, it was the first bike I ever bought for myself, having cut my teeth on 10-speed beaters provided by my parents. I rode it off-road for a while in the 1990s, and it sat neglected for most of the 2000s. In 2010, I fixed it up to use for winter commuting, replacing the old, blown air/oil suspension fork with a rigid front fork. However, that pretty much meant the end of the bike’s days as an off-road, single-track bike.

For a while, I didn’t miss mountain biking, until a few years back, when I started hiking to and from work. From where I live, it’s about a 5 mile hike, about 90% of which is in Patapsco Valley State Park. Problem was, it took me 90 minutes each way, and I didn’t have 3 hours to spend commuting every day. As a result, it became a once-a-week thing, and most other days, I took to the roads on my bike, amongst the ever-worsening rush hour traffic.

PVSP is one of the premier mountain biking areas in the region, and during my hikes, I would always see MTB riders. Eventually, I got to thinking that if I bought a new mountain bike, I could use it to commute on the same trails I was hiking. It would be faster, so I could do it more often, which would mean less time spent on congested roads. In late 2019, I finally took the plunge.

It was a bit of a learning curve picking mountain biking back up after 20 years. It’s a completely different skill set from road biking, particularly when riding steep, technical trails like those in PVSP. But, I soon got into a pretty good routine commuting back and forth from work on single track. Then, COVID hit, and as with everything else, it shook up my mountain biking routine. Now that I’m working from home, I’m not using my bikes for commuting any more, and that includes the MTB. There’s less traffic on the roads, making road biking on weekdays (at least temporarily) more palatable than in recent years. It’s also been a very wet year, and the trails have been muddier than usual. All of this has meant less mountain biking this year than I had planned, though I still try to get out once a week or so. I’ll usually try to wait until 48 to 72 hours after it has rained (tough to do this year), and then I’ll ride a 10-to-15-mile loop before work.

One thing I will say about mountain biking is that, while harder to master than road biking, it is fun. There’s nothing like the thrill of a fun, fast descent, and a long ride on a flowy trail brings on a zen feeling that’s kind of like a runner’s high. You don’t really get that on the road, and it’s been a nice outlet this year. I’m glad I bought the bike when I did, and am looking forward to some point in the future when I can use it for commuting again.

Today, I rode to UMBC and back for a second consecutive morning, and was happy to have no bike-related issues this time around. After yesterday’s adventures, my front tire now has a new tube. When I get around to it, I’ll find and patch the leak in the old tube, and it’ll become my spare. Today, I headed out past Rockburn Branch Park and into Patapsco Valley State Park via Ilchester Rd, Beechwood Rd, and Bonnie Branch Rd. Bonnie Branch was shut down for a couple of months this past summer due to flood damage, and today was the first time I rode it after it reopened. Not too much has changed, other than some pavement and guard rail repairs. I suspect that a lot of repairs were made that aren’t readily visible, though.

UMBC ended all in-person instruction as of Thanksgiving, and sent all of the students home. The campus is really quiet these days, kind of like it was during the stay-at-home order — no one around except groundskeepers and bus drivers. We are living in strange times.

I headed home via my usual route through Relay and PVSP, and when all was said and done, I had logged about 24 miles — not too bad for a chilly morning. The temperature was in the upper 30s most of the time, with overcast skies and a stiff breeze. I wore a wool t-shirt base layer, long sleeve jersey, windbreaker, cycling pants, wool socks, Altra Lone Peak waterproof hiking shoes, and Gore-Tex cycling gloves, and was reasonably comfortable the entire time I was out. It’s going to get more interesting when the temperature starts dropping below freezing. In normal times, I try to keep my rides to about an hour in those conditions, which is easy to do when I’m splitting my rides into a morning and evening commute. I’m not sure my current routine of 2- to 2.5-hour round trip rides in the mornings is going to work when it starts getting really cold. We’ll see.

This morning, I hopped on my single-speed bike and rode to the Seven Oaks neighborhood in Anne Arundel County. I think of this area as Severn, but the addresses actually are in Odenton. The route takes me through the vast industrial wasteland that lies just west of BWI Airport, encompassing the rental car complex and numerous faceless warehouse parks along Candlewood Rd. It then follows Harmans Rd over Route 100 (probably the most bike friendly crossing of that highway west of the B&A Trail) and eventually winds up on Town Center Drive. About 5 miles into the ride, on Candlewood Rd, I broke a spoke. It was on the front wheel, and (as expected) it knocked the wheel a tiny bit out of true, but not enough to make the brakes rub, so I wrapped the broken end around its neighbor and pressed onward, completing the ride without further incident. This was my first broken spoke in quite a while, and I think the first ever on this wheel. My general rule is “break one spoke, replace the spoke; break another spoke, replace the rim”. When I got home, I scrounged up a replacement spoke of the same length and fixed the wheel. I think the “new” spoke came from a wheel that I replaced on my old Giant OCR-1 several years back, as I had about 20 more of the same size in with all my other bike parts. I don’t know if I’m breaking any unwritten rule by reusing a spoke from an old wheel, but if there is a rule, I’m not sure why I kept all of the spokes in the first place. I guess we’ll see how the spoke does, and if it breaks prematurely, I’ll get rid of the others. To my untrained eye, the spoke seemed sturdy enough, so I bet it’ll be fine.

It was not a bad morning for a ride. A little bit cloudy, but mild, as has been kind of the theme this November. It was the second time I had ridden to that area of Odenton (first was in August), and the round trip distance was just shy of 25 miles. I probably won’t get out on the bike again until Tuesday, so glad I was able to ride today.
