It would be nice to know if there is some place up north in Denver/Boulder where there are good trails to train on. The air quality here is just horrible. I ran Jack Quinns on Tuesday and it felt like I was smoking and running at the same time. All the trails are closed due to the suspicion of arson. Palmer Park, Barr Trail, Section 16, 666, Columbine, etc., etc. The only alternative is the treadmill this weekend.
