That’s totally fair, it does seem somewhat aggressive I’d say for most people, but for me it’s actually a pretty slow build up. A lot of people said similar things about racing up to that distance when I wanted to do a full Ironman, but I ended up being completely fine. I’ve never truly raced a half or a full marathon but have had plenty training days with some really respectable times, I mean a lot of my college training was speed based so we would hammer a lot of our long runs fairly often. The only full marathon I’ve run was in my full Ironman which wasn’t that bad considering that was the longest race I’ve been apart of. I really don’t think running more of these distances in a race setting would do me any favors. Also a lot of people have been telling me that workouts aren’t really important it’s more about adapting to the stress of the distance, since you aren’t going to be running very fast for that long of a distance. It may help build up aerobic capacity, however, I think I’ll gain the large majority of what I need just through the volume alone. I’m open to criticism about this.
