I happen to be in a location and a situation very different. If my friends can't get out there are some trails not far away where I can put in a few miles and not too much further from home trails where I can gain some significant elevation and get in any distance I want. If I'm feeling like NOT doing anything I simply put on my (rain?) coat and walk out the door and walk up the hill and get in a half hour.
I am retired and in a place where I can hike or backpack all year long (Olympic Mountains).
