SWAP has had success over the years because of our main coaching emphases:
1. We are here for unconditional support, not just running coaching.
2. All we care about is fulfillment, and we don't give a single f%&$ about speed or results. Those things are a fun byproduct of enjoying the process of life.
3. Every athlete is "elite," pace and distance don't matter.
4. Consistency and joyful daily adventures are what lead to long-term health and happiness. We have built up an active online SWAP community that will be even more important than coaching in some cases, since your teammates will become your friends, confidants, and partners-in-crime.
