I agree with Jen - if you were training for a half or full marathon, and running 30+ miles per week, it may be a different matter.
But 9-12 miles over a week is not going to drive your protein needs significantly higher than what Spark already allows for.
The reasonable man adapts himself to the world; the unreasonable one persists in trying to adapt the world to himself. Therefore all progress depends on the unreasonable man.
