I have one more week with intervals, then a recovery week- when I hope to see that number come back down. I'm not panicking yet.
That sounds a reasonable assumption, I noted that when I was still training for my brevet, before my hamstring problem put a temporary stop to my long rides. You could also be adding muscle as well.
