Hi Archie! The Launch 8 and the Hyperion Tempo are both lightweight Neutral styles and are able to handle the same type of training runs: long runs, tempo, speed work, and even for race day. The Hyperion Tempo includes our new DNA FLASH foam in the midsole compared to the Launch 8 BioMoGo DNA foam This allows the Hyperion Tempo to be lighter, has more energy return, and is more responsive.
