In this 3rd installment of listener questions, we respond to feedback on our Statement of Purpose episodes and answer listener questions including:

- How might you extend marathon training to run a fast 5K?

- What are the practical ways to incorporate additional recovery days for masters if they are following a weekly schedule?

- What do you do about cramps in a marathon?

And more...

Plus, in the intro, we talk about what the US 15K Championship means for Molly Huddle and Jordan Hasay at Boston!
