A simple change that, the person that used flee drops his equiped weapons to the floor insted of in his own bag. I would not include equip tools but it can also be a thing, but I feel bad about poor chased peasents.
Since realisticly if you wanted to run and get a speed bonus you would just drop things that were in ur hands/on you. I would not include droping of armor since it is unrealistic and somewhat harsh maybe.
This will also disencourage needles attempts of failed "hit and runs" that make you waste your time chasing someone around, well if he is going to flee and get bonus speed he has a price to pay also
