 I am so honored that you are sharing this with your viewers. So for those of you who don't do ultramarathons, ultramarathons are hard. An ultramarathon is a race longer than a marathon. The ones that I do are 50 kilometer, 32 mile races. And I do mountain trail runs. And I was in San Jose speaking at SynBio Beta, which is the big synthetic biology conference that my friend John Cumbers runs. And I thought, oh, this is going to be easy. Famous last words. I'm just going to go the day before the conference and I'll run this race.
