Drafting is the essence of group cycling, but many riders don't do it
as well as they could. Here's a technique that'll help change that.
Ride with two or more friends at a moderate pace on a safe road. Form
a paceline with you in the middle, about three feet behind a rear
wheel.
After you get comfortable, move closer. At two feet you'll feel a
stronger slipstream. At one foot, stronger yet. That's the idea.
Closer is better for energy savings. But it also requires more
concentration.
If you let your attention wander, you might suddenly find yourself
too close. If wheels touch, your friend will feel a slight bump
but you could be in a heap. It takes better bike-handling skills than
most of us have to stay up after front-wheel contact.
The instinctive reaction is to grab the brakes when you see the gap
closing to mere inches. But that's the wrong way. Braking should
be the last resort in a paceline or anytime someone is close behind.
It slows you too abruptly and might cause them to do what you're
trying to avoid -- hit
a rear wheel.
Instead, soft pedal. This is the art of continuing to turn the
crank but slowly enough so you aren't applying power. You're coasting
but it doesn't look like it. This should temper your speed just
enough. As soon as you drift back to your margin of comfort, begin
reapplying pedal pressure to maintain the gap.
Soft pedaling makes you much smoother than alternating coasting and
pedaling. Suddenly stopping and starting is a sure way to annoy your
riding partners, too. When everyone in a paceline is always turning
their cranks, it's a beautiful thing.
Two other non-braking tips:
---Sit up. As you soft pedal, this helps you catch
more air
to reduce speed.
---Move slightly left or right. Two benefits: It
slows you quicker by putting you slightly out of the slipstream, and
it makes sure wheels won't touch. Do it smoothly and minimally for the
safety of riders behind. Then flow back in line and resume normal
pedaling.
