Criteriums are great cycling races for anyone who doesn't have the time to devote to endurance training, but is hungry for a little competition. Unlike distance races, which can be upward of 100 miles or more, criteriums usually only last 30 to 60 minutes and emphasize explosive power over muscular endurance. Once you've developed a fitness base, start performing race-specific training to prepare you to dominate -- or just finish -- a criterium race.
Perform accelerations. Criteriums involve constant accelerations and recoveries, so your body must be conditioned to handle them. High intensity intervals on the bike can help you master attacks and breakaways. For example, after a five- to 10-minute warmup, sprint as hard as you can for one minute and then recover at an easy spin for another minute. Repeat the intervals for 10 to 20 minutes, and then end the workout with a moderately intense, steady-state ride of 20 to 30 minutes.
Participate in short, intense group rides. Since criteriums rarely last longer than an hour, it's not necessary to do four-hour endurance rides as a part of your training. Instead, opt for shorter rides of one to two hours with riders who maintain an intense pace for the duration. As a bonus, practice your attacks and breakaways if you train with other racers and the group permits it.
Practice your technical skills. Criteriums usually involve tight turns and require excellent bike handling skills. Have a friend or group of cyclists help you get comfortable with the close quarter contact of criterium racing. At low speeds, practice your recoveries by making light handlebar or shoulder contact with other riders. If you're new to cycling, do this in a grassy field in case you fall.
Train off the bike. Although the majority of criterium training should be done in the saddle, resistance training and plyometrics will help you to further develop the explosive, anaerobic power you'll need to perform well. Use moderate to heavy resistance when weight training, and incorporate plyometric exercises such as box jumps and wind sprints to dial in your criterium training.
