Half Marathon training- week 1

This week was the first of 12 weeks of training for my half.  Before I share how the week went, I'll give you a quick rundown of what my weekly training plan looks like.
Sunday- short
Monday- rest
Tuesday- short
Wednesday- rest
Thursday- medium
Friday- rest
Saturday- long

Last weekend was Disciple Now, so I had to rearrange my days a little bit.

Saturday- 3 miles, average pace 11:44
This was a bit slower than I had hoped, but for the first day, I'll take it.

Monday (MLK Day, so I had the day off work)- 3 miles, avg pace 9:54
I definitely think this is wrong...

Thursday- 2 miles, avg pace 10:33
About halfway through this run, I started feeling some pretty bad shin splints coming on, so I decided I needed to cut it short.  I was aiming for 3 miles, but that just wasn't going to happen.  Given the fact that I had to do some walking, the pace wasn't terrible.

Saturday- 3 miles, avg pace 11:21
This was supposed to be 4 miles, but again, the shin splints.  I think it might be my shoes. I bought them in May, but apparently that's too long to use the same shoes. I went to Dick's Sporting Goods that afternoon to look at shoes, fully intending to get a professional opinion and then purchase the pair I liked on Amazon. #sorrynotsorry. I have a pretty flat arch, so the lady recommended a stability shoe.  Before I even left the store, I bought a pair of Asics GT-1000 3's on Amazon for $20 cheaper than the store.  They should arrive by Tuesday.

Sunday- 4 miles, avg pace 10:54
This is technically the first day of week 2, but since I switched my long and short days, I figured I'd include it in week 1. My friend Melissa came over this morning to run it with me. She's insane training for a full in February and routinely runs about an 8:30 mile, so I was a little nervous about running with her.  She's actually running the half with me (just for fun, might I add) so she was super nice about going a little slower than she's used to. My legs were still a little sore, so I made her walk quite a bit, but even still, I'm pretty happy with my pace.

We're expecting a few days of snow and rain this week, so I may be stuck on the treadmill this week. We'll see how it goes!
