Great suggestions - thanks!

My thought on the training run piece is that you don't even have to think about which runs or races (or even subsegments of runs/races) are your fastest. Just throw everything into the funnel and out come your race predictions. I'll think about how to use the race tag, because that is available through the API.

Training quality is a big one for me, too (especially with a family). I've actually been working on something similar and much larger than just having race predictions.
