Effect: The caster sacrifices part of his/her life force in order to prolong the existence of the rest. When one casts this spell, one takes 100 points of damage. As a result, one's base sprint speed increases to 45 ft/s for the next 90 seconds, allowing for hasty retreats from battle. For the intents and purposes of dodging ranged weapons, the caster's dexterity is treated as 250 or his/her actual dexterity (the higher of the two). The caster may choose to sacrifice more life for more speed and dexterity. For every additional 10 points of damage, the speed increases by 1ft/s and the dex increases by 10.

I like the way the damage scales to feet per second, but the base amount of health sacrificed seems a bit much to boost your move speed by 45 feet per second. So, either drop the base move speed or raise the damage dealt.
Aside from that, I really like the idea of this spell.
