That's not at all what I got from reading the above.

Work accomplished can only be the same if they are both identical in stature, weight, and shape (would make for an odd-looking couple).

If either one is heavier, and there were hills, that person almost certainly did considerably more work, as in more energy expended per unit time. That person would also (likely) have to burn more calories, unless the heavier person was VERY, very fit and the lighter person was VERY, very unfit, and the weight differential was not very great.

Stature and shape also play a part, but to a lesser degree (that's why there are 6' top-level pro cyclists (Jan, Bobby Julich), but no 200lb-ers).
