Love this post Amanda! I hadn't really thought about how big of a deal it was to our relationship when my fiance was training for his first marathon last year. But yeah it was a change in our daily lives for 6+ months as far as time spent away on runs and the sheer exhaustion after long runs. My tips for being supportive? For a few of his 18 mile runs, I would ride my bike along side him. I could give him water and food as needed from my backpack and brought my jam box so we could listen to podcasts as we went. It was a great experience to bond over and helped me to feel like I could be supportive of him (and get a pretty good workout as well). I could also help by having things set up for when he returned from long runs - a towel laid out with his mat for stretching, a drink and yogurt or sandwich, whatever fuel to get immediately after. Or make a big breakfast after long runs. I think little things like that go can go a long way.
