Walter - Thanks for the kind words. And of course it matters! Running is all about sharing and celebrating everyone's triumphs. I had difficuly in 2024 Tokyo as I did in 2023 Tokyo so I am quite impressed with how well you did. And your comparative results between 2023 Boston and 2024 Boston are consistent with my experience and that of the whole "perfect weather" vs. "hot day to run" scenario. Good luck for 2025!
