How often you hear riders say, "I'm feeling languid and draggy to-day.
Can't imagine what's the matter. Had a splendid ride of sixty miles
yesterday." Isn't that explanation enough? The effects of too great
fatigue often last as long as life itself. If the muscles alone were
concerned it wouldn't matter so much, but the great trouble lies in
another quarter. There is always danger of injuring the heart. One can
recover from a strained muscle or sprained joint or broken bone, but let
the heart be once badly strained, and you may be sure that the evil
effects will last a lifetime.

Is there a way of knowing when one has ridden enough? Yes. Whenever you
feel that you couldn't dismount and run a quarter-mile at good speed, it
is time to stop wheeling. Better get off and take a rest. Better still,
put away the wheel for the day. There will be many other days, and you
can enjoy them all the more if you have a sound heart.

Don't wheel up a steep hill. Leave that sort of thing to fellows who
haven't enough sense to go in when it rains. What gain is there in it,
anyhow? You can walk up and push your wheel just as fast, and with
one-quarter of the exertion. If too much wheeling on the level road is
bad, too much hill-climbing is ten times worse. If you could look into
the minds of the smart hill-climbers, you would find that they half kill
themselves to make bystanders think they are wonderful riders. Really,
that sort of thing is too silly to talk about with patience.

Don't coast too much. If you feel that life without coasting is a
mockery, then go to some hill that you are thoroughly familiar with,
where there are no crossings, where you can watch the road for at least
one hundred miles ahead, and then take care. No matter whether you have
coasted down the hill a hundred times before or not, the danger is
always just as great. Perhaps we are never in so great peril as when we
think we know it all.

Don't "scorch" in the streets. At any crossing you are liable to run
over some pedestrian or to collide with a big truck or carriage. Either
one may mean a life lost, or at least broken bones. You wouldn't drive a
horse at a 2.40 gait through the streets. Remember a bicycle is quite as
dangerous.

Don't ride on the left side of the street. Your place is on the right
side, because a bicycle is a vehicle in the eyes of the law, having the
same rights and subject to the same rules as any other vehicle. If
