I signed up for the "Run Through the Grapevine 8K", held at a local winery, after seeing several people in the tri club mention it. It was a bit of a drive, through some pretty rolling hills and windy country roads.
The event itself was tough. Really tough. I thought it would be a trial run, as opposed to a road (or other paved surface run), but it was even tougher than that. Most of the course didn't really have a defined trail - it was just over grassy rolling hills. And between grapevine rows, hence the name I suppose! There was a small stream to jump, a muddy steep trail section more suitable to hiking in drier times, and lots of undulating grassy hills with very uneven footing.
But, it was also a ton of fun. I ran carefully in order to avoid twisting an ankle (there were some tricky sections: curve/turn left while running down a steep part) and finished up in 50:02.
Afterwards, most of us gathered at a club member's house for some hot soup and munchies.
