The energy that is conserved by following is tremendous. Some researchers indicate 30% or greater. My take on the real number is this: how hard is the pace??!! There are times when following saves 0% energy because the tempo is FAST. Riding a bike allows you to follow – or lead. You can lead when you’re not on the front – you can lead in the middle of the peloton. How? By riding safely – by watching out for other riders – by thinking. Lead or follow – riding your bike gives you lots of opportunity for both.
