I'm definitely not hitting the same miles, though I may try to get closer next year. Last year I peaked at 40 miles, and it damn near killed me. This year my injury was after sustained 30 mile weeks, but that wasn't specific to weekly miles but rather muscle/form issues. I'm hopeful I can push past that plateau. A lot of marathon training plans max at 40 miles. These are the plans for people googling "marathon training plan" and not elite or serious experienced runner plans. For me I think if I'm doing a lot of cross training, 40 miles is an acceptable peak. I might buy a Garmin 935.
Do you have a heart rate monitor? Thinking it's about time I bought one.
I do have a heart rate monitor. I currently use a Garmin 230 which uses the chest strap monitor. I found it really useful when I was first starting to run further because it would alarm when my heart rate was too high. Now that I know what too high feels like, I don't really need it. It didn't alarm once in my recent half. The other fancy gizmos intrigue me, especially stuff that reports imbalance between sides. I'd need the fancy watch for that.
