Another ultrarunner? Yes! This week, we've got Mark Manz with us! We talked about his goal to run at least a marathon distance race or longer each month, whether he could outrun a shark, and his experiences at the Cruel Jewel and Desert Solstice. Plus, lots of spicy takes about Gatlin for your listening pleasure.

As we wrap up 2017, we wanted to thank everyone for joining us each week. We're excited to continue in 2018 and hope you are too!
