The Odds

I appreciated a blog post earlier this year by Coho bicycle builder, Charles Lathe concerning riding bicycles and desensitization. His brief story was to explain that he wasn't directly interested in riding in harsh weather other than the fact that it desensitized him to riding in more of the same. If you never ride in cold rain, you'll hate it big time when you do.

Last night on my way home from work I got a flat tire. The tire was a kevlar belted Ruffy Tuffy, a tire I've only flatted once in several thousand miles. I decided to just shoulder the bike and walk home. It wasn't until this morning that I inspected the tire and tube for the culprit. The rubber had de-laminated at the base of the valve stem. There was no apparent reason for why this had happened. There was no distress in that area.

This flat was my tenth in a little over a month. I don't know what the odds are for something like that, but they must be low. It seems like I'd sooner flip ten heads in a row with a penny than get ten flats in one month. I realize that getting or not getting flats on a bicycle tire is not as controlled an experiment as flipping coins, but I have to believe that the chances I'll get another flat in the next 24 hours are extremely low.

I hope.

Here's the tale of the tape:
October 14th on the Coho I get a flat in Mt. Washington in light rain. Fix on the road. I get home and as I'm lifting the bike up on to its hook I hear a hiss from the front tire- a puncture from a small piece of wire.
October 18th during a group ride also in the rain I flat the rear tire of the Kogswell. I find the sliver of glass and patch it. Less than 5 miles later another flat in the same tire-a sliver of glass in a different place.
October 26th pre-riding the On Again/Off Again century ride I flat the Coho's rear on Glatfelters rd.
November 6th I get an immediate hiss from the rear tire of the Coho after (foolishly) riding down the glass-strewn alley behind my house. In the morning the front is also flat. Both from glass.
November 8th during the On Again/Off Again group ride the Kogswell's rear tire's bead pops out of the rim, abruptly (and loudly) exploding the tube. A replacement holds fine for many more miles until while homeward bound, a flake of glass flats the same tire.
November 18th while rounding a corner the front tube on the Miyata fixed gear mysteriously delaminates.

I have spent a lot of time trying to find patterns and reasons for this unlikely string of flats. Riding in the rain is more likely to cause a flat tire. I should not ride in my back alley. Grand Bois tires, while they are fast and pliable, are much too soft for city commuting. However, none of this thinking is likely to change the likelihood of me getting another flat on my way home tonight. At least the ten I've already had have helped to desensitize me when it does happen.

The Final 14



Riders at the start of the BBC's On Again/Off Again


I left the dark parking lot of Oregon Ridge Park having said thank you and goodbye to Andy and Rita. We had just finished the On Again/Off Again century. The sun was down and we were feeling good, hungry and ready for rest. I had suggested dinner together and we considered it. They asked if I was riding the rest of the way home and I said, "no, I'm pretty beat, I'll use the light rail". We wound up not going to dinner. It would've been nice, but it just didn't seem like the right night. Another time maybe. And, then for some reason I turned right on Ivy Hill rd instead of going straight to the light rail station on Beaver Dam. 

I've mentioned here before that I find I get introspective towards the end of long rides. I can't tell you why, but the mind set is always a positive one. Usually I'm feeling appreciative of the physical world around me and if there are other riders in sight, I often admire their physical stamina and riding style. I think about the amazing magic of a modern bicycle- all those smartly placed levers, pulleys  and cables easing and exerting forces on one another and the energy in and out of that system. I see my body as an equally magical secondary system interacting with the first- pressing and yielding to produce nothing more than to get back to where I started.

Ivy Hill rd is an above average climb- sharp, but short. It was, however, enough of a effort to give me the feeling I was transitioning into something new. I had thought I was just "finishing the first ride" or just "heading home", but that hill, the dark sky and the fresh air in my chest all combined to give me the feeling of a new ride begun. And, so I stopped.

Under a rare street light, I prepared for my new ride. The shirt I'd worn for the last 118 miles came off and was replaced by the shirt I'd stripped off earlier in the day. The fleece vest went back on and I felt warmth on my chest. I fished my helmet headlamp out of the bag, attached it and clicked it on. The light beam seemed strong and I pointed it straight down Jerome Jay rd. Several points of light blinked, then moved off to the left quickly. Deer. Warmer gloves went on. I checked my water bottles- both of them nearly empty. Grabbing one, I tipped my head back to squeeze the last bit of strawberry-flavored drink into my mouth and I noticed the amazing texture of stars across the sky. New ride.

From Ivy Hill, Jerome Jay rd has a gentle slope down towards a bridge over a creek. At the bridge there is a short section- wooded on both sides, that gives the eastbound rider a brief feeling of seclusion. The westbound rider wouldn't even notice it because they are most likely screaming down the last of the Jerome Jay hill. This is the hill I begin to climb. I downshift conservatively, staying seated and press hard to see what my muscles would like to contribute to the climb tonight. They seem compliant and I begin a smooth passage forward and up. I swing around the the first of several unnatural bends in the road and I'm into the meat of the hill. For at least one full mile there are no flat spots. My heart rate is going up, but I'm relaxed and managing to enjoy the few remaining slices of woods left in the neighborhood.

I think of Steve Zeldin's short BBC ride several years ago when, as a novice group rider, I cramped both hamstrings trying to shove myself up Jerome Jay. At the time, I acted the martyr and told Steve to not wait on me. He didn't take my advice, instead rolling back down the hill to my position and giving me words of encouragement. I stretched my muscles for a minute, tenderly got back on the bike and began again. Up. I watched the little logos on the back of Steve's bike shoes go up and down, forward and backward ahead of me. His seeming lack of effort while riding up that hill didn't help me, but the bobbing logos distracted me long enough to get to the flatter sections further up.

At some point Jerome Jay rd. becomes Michaelsford rd. I've never known when it does, but the rise begins to ease. The climb doesn't actually crest for another half mile though. Even so, I can feel my HR recovering and I'm still feeling relaxed. I wonder what encouragement I might've given had I been riding with my earlier hamstring-cramped self. Would I have rolled back down the hill to help? Or, would I have seen in myself signs of perseverance and self-reliance and, figuring I'd find the energy to get home, just ridden on, slipping into the dark like a deer? I don't know.

The Jerome Jay hill is behind me as I roll toward Padonia rd, brighter lights and the sounds of heavy traffic. This was by no means the steepest or longest hill I climbed today. Today's century ride was a hilly one- 8,000-9,000ft of ascent. Somehow though, my ride up Jerome Jay, alone, in the dark and after a satisfying 100+ miles was the most meaningful. It was filled with appreciation.

Padonia, leads me to my very last turn- a left onto Falls rd, the road I live on. However, there are still several more miles left to this second ride of the day. The long fast descent past St. Paul's School, the bridge over the traffic choked Baltimore beltway, Joe's bike shop and Mt. Washington, through the Falls/Northern Pkwy intersection (one of the deadliest in the city), past the beautiful homes of Roland Park, the road surface gets ever worse and the houses closer together. I roll into Baltimore city and Hampden. There's a sub shop on the corner where I order my dinner. The line cook gets the order wrong, but the woman at the counter scolds him and makes him remake it for me. I appreciate that.
