I thought about putting this in the "beginning running isn't fun" thread, but to stay positive, here goes.
I went to the LRS this morning to buy new shoes. It's a very nice, very local store, not a chain. Found out that in the past year, they have developed shoes with a wide toe box, but supportive heels. So, my bunion issue and any problems with the stress fracture/shins can be avoided with the same shoe. The owner told me he didn't even sell the shoe I had been wearing, anymore (he sold it to me, though, about 1.5 yrs ago). I ended up with the Mizuno Wave Nirvana. The guy thought I would faint from the price, but after I said, "hey, bike shoes are more," he laughed. He did give me a small discount, which was nice.
Then I went home and bought a subscription to Active.com for the C25K program. I am forcing myself to go slowly. I did the first day, which seemed easy, in the 60 second intervals of running never felt terrible. Of course, most people don't do this on a 10% grade hill, but I tried to time the intervals so only 2 were on the uphill. I did the 30 minutes, and ran/walked 2.2 miles, which is interesting because it used to take me 40 minutes to do this same route, with a short warm up and running the rest of the way. That sounds slow, but remember, I see even very fast runners walk up the hill. The shoes were fine and my foot doesn't hurt.
So, I am not sure how this will play out. Running 3X a week will definitely interfere with my riding and the 2 core/weights classes I am taking. I may be able to double up on the days I take the classes, though, if I run right after the class, in the AM. I know I won't want to run on the days I get home @ 6-6:30. Or, I could actually do a brick, once a week, if I start up my short early morning rides again, soon.
