Frequently Asked Questions

Do I need to be an elite runner to join?

Not at all. Our Slack community welcomes runners at all levels—from first-time marathoners to sub-3 hour veterans. Whether you’re chasing a PR or just want to train smarter, there’s a place for you here.

Can I join Tier 2 if I’m not running a fall marathon?

Tier 2 is specifically designed for fall marathoners targeting peak performance. If you’re training for a different goal, we recommend Tier 1 for now—and we’ll have future cohorts for other timelines.

Can I cancel anytime?

Yes! We offer flexible monthly billing. Cancel anytime, no questions asked (though we’ll be sad to see you go!).

What makes this different from a typical run club or training plan?

We combine evidence-based coaching, community accountability, and real-time expert access inside a private Slack workspace. It’s not just a training plan—it’s a training ecosystem.

I already follow a training plan—why do I need this?

That’s great! Our community enhances your existing plan with expert support, peer insight, and the ability to adapt when life or training throws a curveball. Think of it as your performance edge—not a replacement.
