Summary
The sport of ultramarathon is growing! With that, we have much more exposure to the wide range of events that fall within the ultra category. With growth, we see increased competitive pressure, but not always in a uniform manner. Let's discuss what this means for the different disciplines within ultramarathon, and what we will likely see in the coming years.

| 0:00.0 | Fast forward to today and we have people not only bypassing marathon careers or jumping out of what were otherwise very successful marathon careers while they're still in their peak and doing ultramarathons. |
| 0:15.2 | We're actually asking ourselves what would happen if the best 100 milers in the world would move into the 200-mileers, or if the fastest |
| 0:23.2 | people in the sport from a just an efficiency standpoint like high VO2 max, incredible paces at the |
| 0:29.8 | thresholds and things like that, would start doing things like the backyard ultras instead of 50Ks, 50-mileers, |
| 0:36.0 | 100-milers, and things like that. So I have no doubt that in 10 years, |
| 0:40.3 | when we look at the finishing times of all the 200 milers that guys like Killian are currently |
| 0:45.5 | setting course records at, those will be overshadowed by a large margin. But it's not necessarily |
| 0:50.6 | going to be because Killian isn't as good as them or Killian is a lesser athlete |
| 0:54.7 | than them. It's going to be a lot of it will be because we've layered more and more |
| 0:59.7 | learnings on top of what those guys first guys and guys, guys, guys, and girls first blazed in |
| 1:04.5 | to the, to that process. |
