What’s your weekly mileage like? I went through something similar during RCM training. My easy pace alone dropped over a minute per mile. I was clearly getting stronger, but it took my body a few weeks to catch back up. Good luck with NOLA training!
Thanks so much! I’m hitting between 50 and 55 miles per week, and I’m sure you’re right. Also getting a cold last week did not help, which I was not thinking about when I made the post. We have another marathon workout this weekend, so I should get a good sense of where I stand.
