I was thinking yesterday (I know - it's about time...) as I had 5 hours sitting on the bike - is biking really cheaper than driving? So if I consume 900cal/hour at what really turns out to be 15 mph +/-average on a long trip am I really paying less for fuel? My wife's car gets about 28mpg so let's say it costs $2.50 for every 15 miles. Thats 2.5 nutrition bars or Guu shots or about 250 calories and at about $1/each - it seems I may been better off driving.
I know I am going to get a lot of comments on how to save money on bike food and thats what I am looking for. How can I reasonably carry 2000 cal of food on a hot day for several hours in only my jersey pockets and not need a backpack and do it for less than $5? For this exercise - Drinks don't count. Imagine if I asked this question 2 years ago with gas at $2/gal
