Below, you'll see the asphalt straightaway that follows the start and ends after the red brick building with a hard left turn. Watch out for a few stray metal grates on the ground.
Next, here is the horse show arena from the ground level, from the audience standpoint in the bleachers above, and the exit point we'll be racing through. The horse show arena will house the band, have food and drink as well as large stadium-style restrooms (yay, flushing toilets instead of porta-potties!):
The finish line will be under cover, at the tail end of a motocross track. Here's a shot standing on the finish, looking back towards the rest of the course. Riders will be coming from the right towards where I'm standing.
Since there are no large elevation changes at the Oregon State Fairgrounds, we'll be doing a long run through deep sand to simulate a run-up. Here's a shot from the sand volleyball court area which is big enough to hold several full courts.
The pits will be housed under cover, in the horse warm-up building just outside of the horse show arena. There will be pits located here, the race course will weave into and out of it, and there will still be enough room for teams to warm up under cover from the rain.
Finally, the remainder of the course will be over paved areas, muddy areas, grassy areas, and may even include a water hazard. Here's a general shot looking out on the grounds away from the buildings
