Riding in a group, or sitting on a wheel, saves approximately 20 to 30 per cent compared to the effort required to ride at the same speed when exposed to the elements.
The bigger the group, the greater the advantage, as if you're sharing the workload - as you should - you will have a longer break in the bunch after doing your turn on the front.
Stay close to the rider in front, six inches to a foot off their wheel, in order to maximise the slipstream.
Riding in a close group can be a daunting experience and it takes practice so, if new to group riding, let your ride buddies know so they can offer advice. We also caught up with 1987 Tour de France winner Stephen Roche to find out his group riding tips
If you're nervous about clipping the wheel in front then ride six inches either side of it - but never overlap wheels.
Of course, a lot of cyclists ride solo, so what else can you do to tackle a headwind on your own?
