Building top-end speed for the final laps of a crit seems like a no-brainer, but Im still waiting for someone to convince me that sprint intervals and hill sprints are the only way to go. Whats the deal with all the hate towards longer, more sustained efforts for building crit speed? Are we really saying that a 20-minute all-out effort is useless for building the kind of speed and endurance needed to take the final laps of a crit? Dont get me wrong, I love a good sprint interval session as much as the next guy, but cant we get a little more creative here? How about some longer, more varied intervals that actually mimic the demands of a crit? You know, the kind of stuff that actually prepares you for the chaos and unpredictability of the final laps. Or are we just going to keep doing the same old same old and expecting to magically develop the speed and endurance we need? Come on, guys, lets think outside the box here. Can anyone actually explain to me why longer efforts are so bad for building crit speed, or are we just stuck in some kind of outdated training dogma?
