littlelyonsmanI run Cross Country for a little D3 college in PA so I'm not state champ or anything, but I know a lot about running through doing it competitively for about 10 years now. Just go out and run man. People who don't run can't be giving you advice on how far a day is over kill. I run 6 days a week every week and total close to 45-50 miles a week in season, 30 out. My long runs are close to 10-12 miles on Sunday mornings. You do you man. It will help build up your legs for ski season anyway. If you start to feel sore then bring the milage down a few days or even take a few days off. Ibuprofen will be your best friend when you start hurtin. 2 with every meal of the day usually helps me.
As for the shoes, I run in Saucony Kinvaras or Mizuno Wave Riders
So much wrong with what is being said:
Shoes are a personal preference.
Running does almost fuck all for your leg strength endurance (try doing 400m of lunges, with a barbell loaded to your body weight)
400mg of ibprofin with every meal, or even some of them, will do more to fuck your liver than the next four years immas spends in a sorority. Take it from someone who is 25 with a broken body, where the good days are when you wake up and your hip pain doesn't make you want to punch a homeless man for bein poor. Mobility and strength balancing (re: Yoga motherfuckers, do it) will do more to help you out than drowning your poison filter in NSAIDs.
(And I got bottles of 800mg Motrin and 500mg Naproxin pills for days).
Just to re-iterate. running, like whisky, women, and warfare, is great, but too much will leave you broke and bloody on the side of the road.
