3 weeks vegan - last long training run

I've been eating vegan for 3 weeks now. I feel great, not that I got through the detox period. It takes me a lot longer to plan meals and shop for food now, but it's worth it. I know it will come easier the longer I do it. Also, I ran my last long training run, 12.7 miles, this morning. My pace was good (better than I expected). My sweet husband carried my water bottle and rode along beside me on the bike while I ran. I appreciate his love, support, and protection so much. I am so blessed. My muscles are "talking" to me right now - 6 hours later. I am going to be so sore.
