How about 1 Cor. 10:31 -
So, whether you eat or drink, or whatever you do (run), do all to the glory of God.

Can we glorify God in our running? How do we do so, and how is it apparent to others?

Or 1 Thess. 5:18 -
Give thanks in all circumstances; for this is the will of God in Christ Jesus for you.

Not only when training and racing well, but even when sick or injured, after a poor race, or when PR's are a thing of the past.
