Starting to ride to work more.
I know my fitness will improve over the coming weeks/months but, allot of my ride is on busy commuter routes (24 miles all together). I'm very conscious of the car fumes as I ride, which got me wondering.
Are the benefits of me cycling ie being healthier/fitter/longer life expectancy of being fit, wiped out by the nasty things I hoover up as I cycle ie nasty chemicals effecting life expectancy/lung capacity? It almost feels like I'm having a fag on the bike as the cars accelerate past me.
