A few days ago I did the Red Rocks 5K with Kary.
Unlike a more likely 5K, this race starts with of a lot of downhill followed by an uphill trudge ending with a stair climb. The race course basically took a clockwise loop around Red Rocks starting in the upper north parking lot and then ending at the top of the amphitheater.
I did plenty of 5Ks in high school and then others throughout the years but this was the most unique grueling course. A lot of 5K courses usually have the same moderate amount of elevation loss and gain - or are basically flat - but this one had the most loss and gain I've ever done. Most courses I've done have had probably 300 feet total of elevation gain and loss but Red Rocks was more like 1000 feet. Most courses have you finish with a flat to moderate grade but Red Rocks was a stair climb to the finish.
With altitude, cold weather and so much climbing it was going to make for an interesting day. Additionally, since some "officials" on the course were not course guides, the group I was in took a wrong turn (while one of these guys was watching us take the wrong turn!) that resulted in us going about a mile extra. Luckily there was another official closer to Morrison Road that turned us around. Regardless, if wasn't pleasant to do an additional mile with so much uphill basically for the last mile and a half. My quads and calves were killing me the next 3 days.
I'd be pissed except that it was for a good cause.
Back in Boulder we were able to pig out on sausage egg cheese muffins and then take a nap later.
