Normally I drive at least once a week to pick up groceries at a store close to my work. Usually lots of fruits and veggies. But today I thought I'd take the groceries onto my bike rack with the two pannier bags, and my backpack. I must have packed a good 30lbs of stuff onto those two bags and the backpack.

Anyway, my query is, is it tougher to ride with a full load of groceries in tow or to ride against the wind? As luck would have it I had to do both today so I couldn't say which one made the journey so hard.
