review of 2016 Colorado Marathon.   

3 / 5 Stars


Beautiful course. Not very good support on course. Hate the zero calorie drink offered.

Race Tips

The last 10 miles is long slow grind...don't go out too fast.

Fort Collins is awesome. The afterparty is the best.

review of 2014 Colorado Marathon.   

3 / 5 Stars


Don't let the downhill fool you. This can be a challenging course due to altitude, downhill grade on the quads, odd pitch road camber on the downhills. Also the water stops are short and not always quick at getting fluids to runners. The water stops may actually cause you to stop to refuel properly. While there are 12 water stops the first few have you running almost 3 miles to get them.

Race Tips

The first 16+ miles of the course is a runnable downhill. The issue though is that the runners must run along the left side of the road. The right side is left open for vehicle access even though not many cars are seen due to the early 6:30 am start time. The camber of the road going downhill on the left side tends to force runners to always be leaning to the left side. Thus forcing more straining on the left leg, and calves. Running with a pace group may work best on this race. I ran solo and it got pretty lonely out there as few runners were running a 3:10 pace nor were there many cheering groups along the first 20 miles.

Host Hilton is nice, but not close to the finish line. I would recommend grabbing a hotel near the finish - much more to do there then at the Hilton.
