Identity Crisis!

OK, so the die is cast, and planning for the next step in our evolution has begun. Hmm... "Evolution"... no, too generic. Sorry. Anyway, I'm planning to turn us into a full-fledged training program. As much as "Team In Exile" is fun and apropos, it's limiting. So, we need a name.

Criteria and thoughts:

• It needs to embody our central philosophy of running (no, not the drinking part), which, roughly stated, is that we're using sports like running and biking as opportunities to explore, challenge, and expand our limits. I briefly settled on the word "mettle", which is defined as "heart: the courage to carry on", or "inner strength, spirit and courage." I already think a possible tagline is, "Prove yourself." Anyway, I just don't think the word "mettle" has the right sound.
• It's gotta have the right sound. I'd like a single word that we could combine with "Athletic Training" or "Training" or something. It ought to be good for cheering at races. It should look good in print, too, for logos.
• No animals, nothing too macho, nothing that is so elite performance-based that it will scare off beginner runners.
• No names of bizarre sexual positions, Mango.

So. Whatcha got?
