My 2 cents
first off I hate the Dreadmill but I am finding it may have its advantages. I have been running on the indoor 1/8th mile track. When doing 5 miles that is a lot of corners and the inside of my lower leg has been sore. So I may alternate between treadmill and track if the direction on the track is the same for my running days.
Also I am pretty sure I will use it when I start intervals and tempo in a week or 2. There is no way I would be able to pace myself on the track.
I am waiting for the snow and ice to go away so I can't get outside - The weather has been beautiful but we can't even run on the street. We have had so much snow that 4 lane roads are down to 2.5 and 3 lane roads are barely 2 and the 2 lane roads cars wait for one to go through because they are about 1.5 lanes - No room for runners and do you think people have shovelled their walks? ? ? ? ?
It's about the journey and being in the moment, not about the destination
