It will be different for each individual.
Oh, I concur -- I simply meant that it's
closer than the amount of work involved in running a mile in 7 or 8 minutes vs. riding a bike at 20 mph for an hour. For a person of 75 kg, running a mile at a 7:30 pace is an output of around 120 kJ. That same person riding a bike at 20 mph for a full hour is going to be putting out something like 6x as many Joules, around 720 kJ. So riding at a pace of 20 mph is definitely "easier" than running at a pace of 7:30/mile -- but the other comparison was ridiculous.
