Since I'm not riding as often as I used to, I took on a project to keep me busy
It's called Zeias (pronounced zee-iss / zee-us) and is a pacing device for running athletes (track and field, marathon training, athlete conditioning, etc.). It's been coming along pretty quickly the last couple of months, so I'm stoked! The best way to think of it is the rabbit at a dog track without the inner rail. It straddles a lane line on an athletics track and is programmed to steer itself along the line (thus having an "infinite" loop), and the athlete can input distance and time, flip the switch, and follow it around the track. I even have it programmed right now for interval work, so one of my workouts is a 300m run, 100m recovery walk, repeat a total of 6 times. I post videos on Instagram, so here's the link for that so you can see exactly how it all happens:

Endurance-wise, I haven't tested it all the way to the low voltage detection shutoff on the truck, but I estimate that it'll run for a solid 40+ minutes at a 6-minute mile pace, so pretty good for a long track workout. I only use ~20% of the battery when I do my interval workouts so it's never an issue. The truck is also capable of going 60+ mph, so plenty of speed for the sprinters
If things go right with some fine tuning over the next several days, I'll be taking a little road trip to Florida to train with my old college team and a buddy that is training for Rio (ran at London in 2012 too). Pretty pumped for it! Here's a pic of the little beast...
