My biannual cycling mileage totals for the past three years:
2008 (H2) = 1600 miles
2009 (H1) = 1100 miles
2009 (H2) = 1400 miles
2010 (H1) = 1500 miles
2010 (H2) = 3500 miles
2011 (H1) = 3700 miles
of these 10060 miles were commuting miles or at least miles cycled instead of using my car, this roughly equates to £1845 (given the cost of petrol at the time plus 5p wear and tear per mile). Of course if I didn’t still have a car the savings would be three times this, but the car costs me money even if I don’t drive it anywhere!
The reality is that I took up cycling as my main hobby and stopped my other sporting activities, in doing so this money has paid for about half of my cycling hobby, which is a lot less than I was spending on either of my previous hobbies (football and badminton). Of course, most of the three years I’ve been collecting clothing, tools and a couple of bikes, so the hobby cost will keep falling (unless I keep buying bikes) and maybe even end up being a hobby that pays for itself (or even better; a hobby that truly saves me money).
