sleeping in late. getting a massage. lying around on the couch, the only activity being lifting a glass of wine to drink. having ice cream with hot fudge sauce for breakfast. not cleaning the house or doing laundry cause it hurts too much to go up and down stairs - these are all good things to do, or not do the day after a marathon.
but i think my personal favorite is the thing i did late last night: my husband had just left with friends to go mountain biking. in the snow. cause there was a real honest-to-goodness blanket of it outside. he was like a little kid getting dressed to go out sledding in the first snow of the year - he was so excited. and when coach & his wife pulled up on our lawn and my husband headed out with them, it looked like it was going to be fun. and i had snowy activity envy. but activity was something my screaming quads were not really interested in. but that snow! i couldn't help myself. i had to do it. if the forecasters were right, it would be covered with ice by morning.
i dug out my ancient xc skis, poles & moth eaten boots, and cross country skiied for an hour on the streets of my neighborhood. my quads stopped screaming at me for just a little while and enjoyed every stretchy stride. it was quiet and would have been much darker if it weren't for the blanket of bright snow. ginormous snowflakes were falling on my face. perfectly dreamy. once home, i resumed my spot on the couch and had some more wine. which, after cross country skiing may be my second favorite post marathon activity. fittingly, it is also a good apres-ski activity.
