I don't think daily is too much. When I was in my best running shape I would run every other day and make whatever day fell on a weekend a long run. Back then it was 3-4 mile runs for the easy ones and then a 6-8 mile run on the weekend. This was in training for a 1/2 marathon. If you have any running questions, cliffelam was my running guru and I'm sure he could steer you in the right direction. I am on my second pair of Brooks "Ghosts" and I really like them a lot. I know resources are slim when you are a college student, but investing in a good pair of running shoes isn't a bad idea if you plan to stick with it. As cliffelam will tell you, many people run too long in a shoe and they can be harmful at that point or even dangerous. 1.3 is a respectable maiden run, I hope you stick with it and enjoy it. edit: I just finished two sets of tennis and had a blast. It's fast becoming one of my favorite past times.
Well, I did 1.3 yesterday and 2.9 today. My legs are not happy. I think I'm going to do the every other day routine. I'll be aware of if these shoes make me uncomfortable. If they do I'll throw down on some shoes. The local running shop gives a discount to students which is nice. Who do you play tennis with?
Or run in proportion to how much beer you drink? Haha, just kidding. I might have a beer or two a week so I think I'm still in the clear.
