I am 99% trail. I did run the roads this winter when we were under 2 feet of snow, but I do not do it unless forced. I NEVER run on the treadmill. I will get up at 4:30 am, I will wear spikes and run in the snow, the rain, the mist, the hail....well you get it. No treadmill for me.

This is what I said to Amanda....

Aside from proper footwear, keep in mind that trail miles and road miles are not the same. You will use a lot more of your lateral stabilizing muscles because of the uneven terrain. It is very easy to get injured if you jump in with both feet. Pun intended.

I would suggest that you start with short runs, regardless of your current road mileage to give your muscles, tendons and ligaments a chance to adjust to the demands of trail running.

Also remember that you will be slower, so fuel and water will become an issue sooner than on the road.
