I'm definitely slower at 49 than I was at 29. I have better endurance but that's at least partly due to training for it. I'd like to think I race and train smarter now. I'd also like to think that there's no performance cliff waiting, where one year I'll just suck no matter what I do. Actually this year's been like that, but it's been due to health problems. Which may be a sign of old age. What was I talking about again?
