Yep adding Wurf in the mix really does spice things up. As you saw on Sunday, you've got now three uber bikers in Wurf, Kienle and Sanders that can all work together, bridge the gap and then gap the all-rounders and fast runners. If the second group gap in the swim narrows next year (based on post race interviews, it seemed their pace was slow) and Sanders improvement continues + better marathon pacing, the other guys are in trouble. Will another uber biker in Talansky change the dynamic next year? probably not - three's a big enough crowd.
I think Frodo was a bit torn on the weekend, as he might be in coming years. He doesn't have the full bike strength as the uber biker group so was probably maxing out or even over biking, trying to keep up with these guys. He also can't ride too conservative with the potential of Lange coming through on the run. I'm guessing next year he will learn towards being more conservative on the bike and then look to lay it down more on the run. But the question is balancing the time gaps into T2 - I'm guessing you only want to give Kienle/Sanders 3-5 minutes but be in front of Lange by 3-4 minutes also.
