To make Geralt faster early on, get one of the first warrior path skills (unlocked at level 6-7 by putting points into the Witcher path). The warrior skill allows you to dodge farther distances (level 1 is %100 and level 2 is %200). While in wide open areas or even in a deserted part of a city, pull out Geralt's sword and begin to roll. This will get you wherever you want to go much quicker because, if you time it right, you can roll without pausing in between rolls. Note: If you attempt this near guards they may pursue you. Simply put your sword away as soon as they try and they will leave you alone.
