I don’t think it is an either or aspect, more so a slight shift in philosophy toward Tellez, Bush, John Smith, or Winter. Smith and Tellez will start with more volume and slower work, call it tempo, and work their way down to less volume, more rest, and faster times. I don’t know of any that have fast 100/200 people who ONLY do tempo. They all have starts, accel, and most have 60’s, etc. They just don’t necessarily use tempo like Charlie, as a year round conditioning component. Instead more like Ext tempo –> Int tempo –> to Speed End though I haven’t seen any define it like that.
