Wonder if any of you meatheads on here can answer some questions I have about running. I see a lot of training programs saying that they keep weekly mileage under 25. Why? I'm around 20-22 miles at 5days/week and feel like I could (and plan to) do more without much of a problem. While distance/endurance running seems surmountable, I'm having trouble increasing speed. Any tips aside from fartleks? The problem I have with fartleks is I have one speed: slow. I don't have much trouble running for 50 to 60 minutes, but it is always the same speed. I need those /ana/reobic Do long distance runners normally run without underwear? I've seen people talk about having trouble with chafing until they bought shorts with netting. It doesn't seem like this would be needed unless they're going commando. I had trouble with my inner thighs chafing when I was just wearing mesh (swishy) shorts and cotton boxer briefs, but haven't had any trouble wtih chafing since I bought more running focused shorts and still wearing the same underwear. I've been trying to prepare for outside running during the winter. I see a big focus on shirts that wick moisture away. Normally, I wear cotton tshirts and after my runs I'm drenched. I understand I won't sweat as much on a cold, but even on a 70 degree day my chest and back are soaked through and with wick material that moisture is has to go somewhere. My shorts are supposedly fast drying and wicking, but they're always soaked through too (or is it because of my cotton underwear?). So what's the point of fast-drying wicking material on cold days if you still end up drenched in sweat? On the bottom half of my body during winter runs, I've read that at most you need to wear tights underneath your running shorts. So am I supposed to go commando? Because as I've said above my underwear are drenched in sweat when I get done running. On a completely subjective note, how bad is it to run in cold air? I've heard it is like daggers, from people who have never been stabbed, but yea, is it something that I'll be able to get used to in a week or two or three? I've heard that REAL running shoes make a big difference. I'm barely an athlete, I want running to be a habit for me, but I'm never gonna be able to compete other than against myself. Do I need a $200 running shoe? How hard is it to switch running shoes? I have a pair of Adidas that I've run in since the beginning of this summer. At the same I bought those (cause buy 1 get 1 half off, bullshit) I bought a pair of new balance that I've only run in a couple of times recently on shorter runs. Finally, how many miles do you think I have left on my shoes? pic related
