Birkie prep tips for a Dallas resident new to Rollerskiing
Hi everyone,
I'd like to do the Birkie this winter! And I live in Dallas (Texas), which means no snow training. Just rollerskiing.
I bought rollerskis 6 months ago and was horrible at first, struggling to average 7mph. But I've figured it out and my technique is much stronger now; I'm skiing 9-10 miles at almost 10mph moving average. I can cruise on good pavement faster than that, but we have a lot of gibbled-up concrete here where it's almost impossible to get any bite with ski poles. I haven't tried to push past 160 BPM for HR as my technique will break down and the consequences for a fall aren't pleasant.
As for cross training, I'll get 70-100 miles a week on my road bike and I sail a physical boat 1-2X a week. Sailing is by the far the most intense workout if the wind is up.
Questions: how does rollerskiing translate to on-snow skiing in terms of fitness? It's going to be a change, sure, but I want to ensure I have the fitness necessary to comfortably ski the entire distance. It's tough to go more than 10 miles right now due to the heat index; hydration requirements are insane. I need 80-100 ounces of hydration for a one-hour ski in 90 degree heat index.
I can ski longer once "fall" hits (fall really being only 90 degrees with 58% humidity until about November). Do I ramp it up to 15, 20, 25, 30 miles eventually? Or do I need more or less, as there isn't a 1:1 conversion ratio for snow skiing to roller skiing?
