I'm going to take that philosophy to heart a lot more this winter, as I plan on doing quite a bit of snowshoe running. I have five races on the calendar and as long as there's snow, I'll be incorporating a lot of the snowshoes into my training.
How this affects the Boston training is debatable. No doubt it helps in a big way, but just makes things very tricky to gauge. To kind of help with that, I'll experiment with guesstimating what pace it would translate to if I were running on roads, based on my breathing and effort.
For example, today's 4.2 mile jaunt out back was probably around a 7:30/mile road pace effort overall, and that's being conservative. It took a little over one hour and six minutes, which translates to an 8.8 mile road run. Keeping that in mind will help with what might look be a sacrifice in mileage, but is in reality high quality hay in the barn for the same amount of time.
The snowshoe run itself was great. I took the same path I did yesterday, so it was at least semi-broken in for the first mile (it snowed some more yesterday after I got back and plus the wind blew things around a bit). After that, it was breaking trail again for a little less than a half a mile.
That brought me out to the fire road, where a snowmobile had gone by. Sweet! Though it was already starting to get dark, I couldn't resist and did an out and back in its tracks for a little over a mile total and then took the path home. Great run, and I just beat the dark.
