Roller ski skate 1:00:00  10.19 mi (5:53 / mi)
At east end of Poudre trail. I put on brand new tips on the triac's to see how they worked compared to the trekking pole tips. They give relatively good grip on concrete, slipping maybe 30% of the time. The sound is annoying for sure. The trekking pole tips slip more, but they behave predictably and are quiet and smooth. Not sure which is better. It appears more unlikely I can get my hands on some X-Curve poles, no response from "the source," and perhaps they are no longer made. Also, "Andy" from Nordic Team Solutions didn't have much useful info for me. I'm tracking down an aluminum welder, maybe I can make my own. 30 minutes of the ski was on concrete with the triacs and the tips were noticeably duller, probably can get maybe 3 skis max before major sharpening is needed.
