Your Turn: Road Cycling Skills

Road cycling - especially on a cross-country journey - requires some comfort and experience with cycling on busy roads with fast-moving traffic. The most important preparations I made over the two years I planned this trip were getting used to cycling on roads in New York and its surroundings including a five-day trip from New York to Montreal.

Road conditions:
The truth is that a substantial fraction of a cross-country trip requires you to cycle on roads with fast-moving traffic. While intelligent routing can limit your exposure to high traffic areas, some 70% of your journey will require riding on two lane highways with a speed limit in excess of 60 mph. Rare will be extended periods on paved bike paths or residential streets.

The most important principle of road cycling is to treat your bike like a vehicle - never ride against traffic, obey lights and stop signs, and ride predictably as if you were driving a car. As a cyclist, you have full rights to use the highway (freeways and interstates are usually the exception where bikes are typically prohibited), but as a practical matter, you are expected to ride as far to the right as safe.

On highways, the vast majority of cars and trucks will pull over to the other lane to pass. However, the occasional driver will not, passing you quite closely. Holding a steady line will minimize any dangers from close passing traffic, though the experience may still be unnerving. Drivers deliberately running cyclists off the road is rare (and has never happened to me), but some other cross-country cyclists I met on this trip reported such incidents. In these cases, it's important to try to keep your bike straight on the grass or gravel off the road. A fully loaded bike is fairly stable, and unless you are traveling at high speed, you should be able to keep control.

Using the shoulder:
Roads with a generous shoulder are a cyclist's friend and form a de facto bike lane in many areas. Moreover,  the size of shoulder typically correlates with traffic volumes. Avoid riding too far to the right in the shoulder -  debris from the roadway including metal and glass pieces that cause flats accumulate there. On busy roads, rumble strips on the left side of the shoulder will naturally form a barrier between cars and cyclists.

On highways with narrow shoulders or otherwise rough road, you may be forced to ride on the white line or even ride inside the lane itself. Moreover rumble strips may force you to ride in the lane even if the highway has a narrow shoulder. Several stretches of US-12 in South Dakota featured these conditions. As long as you maintain visibility and ride predictably, riding inside the lane should not be a problem. It may inconvenience traffic that is forced to slow down, but as a cyclist, you are within your rights to take the lane. Indeed, in high traffic situations - in suburbs or on bridges - it may be best to move to the center of the lane and control traffic behind you.

At faster speeds in a tailwind or during a descent, ride further away from the road edge towards the lane. You are more likely to lose control if you ride off the road and injuries would be more severe.

In the end, riding on the highway with traffic is an act of faith. The likelihood of a sober driver running into a cyclist from behind on a clear day is minimal, but injuries would probably be severe in case of an accident. The vast majority of cycling accidents occur in urban areas at intersections.

Maintaining visibility:
On the open road during daytime and good weather, a cyclist will be fairly visible to cars from a distance. However, on highways, it is generally advisable to take further precautions to maintain visibility to drivers. I always wore bright colored clothing and, on the busiest roads, I typically wore a reflective yellow safety vest. My rain jackets were also brightly colored, and, in the rain, I attached a blinking red light to the back of my bike to improve visibility. I did not have to ride in foggy conditions or through heavy rain - in those conditions, it is advisable to wait for conditions to improve.

Riding the interstate:
Cycling on the interstate is not permitted in most states outside of the West and is certainly not advisable in suburban or urban areas. However, in many western states, the interstate may be your best (or only) option. I traveled on the interstate several times in Montana and Oregon and generally found the interstate to be easier to ride on than many highways. Shoulders are nearly always in excess of five feet and multiple lanes allow traffic to pass comfortably. Moreover, with a divided highway, oncoming trucks do not buffet you with a gust of headwind as they pass by (in contrast to a two-lane highway).

However, pay attention at on ramps and off ramps - as a cyclist, you take several seconds to cross the entrance/exit lane and cars may misjudge your speed. Also, shoulders on the interstate can narrow or disappear on bridges.

NB: This post and previous posts is merely intended to provide advice and impressions gathered in my time road cycling and during my cross-country journey. It should not be construed as advocating for cross-country cycling or declaring that road cycling is a safe activity. Road cycling carries considerable risks that must be weighed by any prospective cyclist.
