Often times indoor, or trainer workouts are most closely associated with road riding. The thinking is that for off road athletes to be successful they have to perform all of their workouts on the trail. That’s simply not the case. In fact mountain bike athletes can see tremendous gains from the focus and specificity that indoor workouts provide. The ability to hone in on the nuances that make racing and riding off road exciting, will also produce substantial fitness gains for those looking to improve in the discipline. We’ll take a closer look at some of those nuances, and examples of the types of indoor workouts that can help athletes prepare to be more successful off road.
Preparing for Climbing
More often than not MTB races include some form of climbing. Depending on the terrain, and the geographic location, climbs could range anywhere from a few minutes to a few hours. Below is an example of a workout that will help to prepare the body for climbs anywhere in the 5-20 minute range. The first 2 minutes of the main set should be completed standing at 120% of FTP, then perform the following 8 minutes seated at 97% of FTP. Intervals can be added as fitness increases.
There’s a few areas that this particular workout helps to bolster. One is building muscular strength to be able to produce efforts at, or just below FTP. This is a valuable area to focus on for all riders, and climbing is just one area where it’s important. The structure of this workout encourages FTP gains, as well as develops the anaerobic system when energy from that source is needed. Working on maximum aerobic power, and the ability to draw from both the aerobic and anaerobic systems is critical in the development of a mountain bike racer.
Preparing for Short “Punchy” Efforts
Not every feature on a race course is a long epic climb. Sometimes a course consists of relentless rolling, or “punchy” hills that can wear even the most seasoned rider down. Short, high intensity efforts lasting 5 minutes or less are also worth preparing specifically for. Even on big mountain courses, the developments from a focus in this area will prove worthwhile. The following workout will help prepare the body for the demands of these short maximal efforts.
After a warm up the workout focuses on sub-threshold work with a series of progressive surges mixed in. The first set is to be performed by riding for 2 minutes at 92% of FTP and then surging for 30 seconds at 110% of FTP. Then after a short recovery period the next set builds on the first by calling for 3 minutes at 95% of FTP with 30 second surges at 115% of FTP. The goal is to try and do at least 4 of these surges per set, increasing as fitness is gained. The focus on supra threshold efforts helps to develop the body’s lactate clearing potential in which the body is able to process lactate as fast as it’s produced. When this occurs it allows the body to continue to absorb calcium at an appropriate rate and facilitates proper muscle contraction. The more developed an athlete is in this arena the harder they can go, and the more times the effort can be reproduced, when a maximum effort of 5 minutes or less is needed.
Preparing for Fast Starts
Most mountain bike events begin as a mass start race where it’s a free for all once the gun goes off. Mastering this component of the race isn’t just a good strategy for securing a top position once the race goes to singletrack, it also requires a lot of effort from a dead stop. This, like all skills, can be developed with focused workouts.
This workout is a bit of a “mixed bag” session that not only focuses on a riders ability to produce maximum effort from the start, but also their ability to settle into sustained sub-threshold zones after those efforts. Typically after the start, and the big sprint(s), the work isn’t over. The rider has to work to maintain position, thus the need to train the body to handle this type of effort. After the 45 second sprints at the start of the workout, and with very little recovery, the intensity drops to 85-90% of FTP for 10 minutes. It then moves to progressive intervals that transition from 3 minutes at 95% of FTP to 1 minute at 120% of FTP. Training the body to cope with the sudden onset of blood lactate, as well as the ability to regain composure quickly after the big start, is as much about physical adaptation as it is mental. This session covers all of the bases to help off road athletes prepare for a traditional mass start race.
The focus that indoor training can provide for an athlete with a mountain bike centric season can be invaluable as those athletes look to prepare their bodies specifically for the rigors of the sport. Regardless of whether the discipline is XC, marathon, or ultra-endurance these types of workouts will help to facilitate the areas of adaptation most valuable to mountain bike racers. Make the most of any available training time by honing in on key areas, and preparing the body specifically for what it will undoubtedly encounter on race day.
