You are a Small character with a Strength of 8 (adjusted). So...
Light Load = 0-26 lbs (Move speed 20)
Medium Load = 27-53 lbs (Move speed 15)
Heavy Load = 54-80 lbs (Move speed 15)
Lift ability (over head): 80lbs
Lift ability (off ground only): 160 lbs. (lose Dex bonus and move at 5'/round as full-round action)
Drag ability: 400 lbs.
The other effects of your Load will be:
Light Load: No penalty, Run speed (straight line) x5
Medium Load: max Dex mod +3, skill check penalties (STR based skills) -3, Run speed (Straight line) x4
Heavy Load: max Dex mod +1, skill check penalties (STR based skills) -6, Run speed (Straight line) x3
Being so small and physically weak, you will want to be very careful about how much you carry.
How did Adrien get around all that? Why, with his loyal (pack) dog, Tar, of course.
