Your Indoor Trainer: To use but not abuse
As we prepare for the 2015 season, the majority of us are affected by the weather or by the Daylight Savings time change. Either way the indoor trainer becomes necessary evil. While riding indoors can be mentally taxing, there are benefits to be gained by logging time in the hurt locker. As long as you are able to get outside once or twice every two to three weeks for a long ride, the trainer should be used for quality over quantity. The trainer is a crucial part of a winter program. Since I began racing in 1986, never once have I ridden more than 2 hours indoors.
Indoor Time vs. Outdoor Time
In comparing indoor vs. outdoor time, there are three important factors to examine. First, doing a 60 minute indoor ride would roughly equal 90 to 100 minutes of riding outside. Why? The work is steady for the entire indoor ride. You are constantly applying pressure to the pedals; there is no coasting, etc. Given this, you are doing, on average, 50% more work when riding indoors. Second, you need to consider your static position while riding on an indoor bike. Even if you have rollers with a “motion” device or a trainer that allows the bike to rock, your position changes very little. Riding outside requires adjustment o ever changing terrain. Your body position both in and out of the saddle changes in many ways allowing you to work different muscles. On your indoor bike, you are constantly working the same muscles for an extended period of time. This especially applies when doing structured efforts. The lack of variance in your position can cause certain muscle groups to be over-worked and others to be under-worked. One caveat is that riding an indoor bike, especially rollers, can be an excellent way to smooth out your pedal stroke and to help find any dead spots in the stroke. Finally, you have to consider the mental factor of riding indoors. Even the most mentally strong individuals, will eventually reach a breaking point when riding inside. Since the trainer is such a valuable tool, great care should be taken to use but not abuse your indoor time.
Use the three guidelines above to remember quality over quantity. Indoor rides should last anywhere from a 30 minute recovery ride to a 2 hour structured effort. Most rides should fall in the 60 to 90 minute range.
Structure: Building a foundation for fitness
Have a plan for your indoor training period. Ask yourself, “When do I want to be at 80-85% of fitness?” Most of us want to go into the end of March race ready and have a solid base of fitness but not bang on form. After you determine that date, you want to allow 3.5 to 4 months of indoor training in your schedule.
Remember periodization. You want to work in 3 to 4 week blocks and then take 4 to 6 days of rest. Then resume training.
It is important to let your body get back into the trainer groove. Allow 4 or 5 rides at 20 to 40 minutes of low intensity to adjust to being inside. Once you are comfortable with riding indoors, use the following phases to guide your plan:
Always: Do a 10-15 minute warm-up, a 1 X 5 at LT and at 95-100 cadence followed by a 5 minute recovery.
Phase 1: Lactate Threshold Work (first 1 to 1.5 months of program)
One of the best ways to increase your LT is by doing 20 minute efforts at 92-95% of your LT.
Do the warm-up as described above then do 2 X 20 at 92-95% of your LT and at a 90+ cadence. Do a 10 minute recovery between efforts with a 5 minute cool down to finish the 80 minute session.
Frequency
Monday through Friday: Two rides per week at 60 to 80 minute sessions. Do 1 or 2 effort days with a recovery day between.
Weekends: One to 2 rides at 60 to 80 minutes per session. Do 1 effort day and 1 recovery day.
Phase 2A: Mid Intensity Effort Work (1.5 to 2.5 months of program)
Here, the interval duration is decreased but the effort intensity is dialed up.
For the 10 minute efforts, do a structured warm up then do 3/4 X 10 at 100-107% of your LT and at 90+ cadence with 5 minute recovery between.
Frequency
Monday through Friday: For first 2 to 3 weeks of phase, do 1 per week with other rides being LT, tempo or recovery. After initial 2-3 weeks do 2 per week.
Weekends: One per weekend. Other day LOW Tempo or Recovery
Phase 2B: Mid Intensity Effort Work (2.5 to 3 months of program)
The 5 minute effort can be some of the most painful intervals. Short but very hard!
After warm-up, do 4/5 X 5 at 110-118% of your LT and at 90+ cadence. Recovery time becomes very crucial here and should be at minimum 100% of effort time.
Frequency
Monday through Friday: By now, you are ready for multiple hard days in a week. You can mix in 2 per week.
Weekends: One per weekend. Other day Tempo for 1 hr OR 2 X 20’s at LT.
Phase 3: High Intensity mixed with LT Maintenance (Final 3 to 4 weeks of program)
The final phase of your indoor training should be a mix of 1, 2 and 5 minute efforts.
These will help peak your fitness as you approach the end of trainer season.
You can do a ladder of efforts: 1/2 X 5 at 110-118%. Then 3/4 X 2 at 120% and 5/10 X 1 at 120-130%. Again, recovery times should be at minimum 100% of effort time.
Due to the very high intensity of these efforts, it is important to work in frequent recovery rides during the week. Also advisable to do 1 LT ride every 2 weeks to maintain base fitness
Frequency
Monday through Friday: Two per week. Other days being Recovery or Tempo
Weekends: One per weekend. Other day Tempo for 1 hr OR 2 X 20’s at LT.
The trainer can be used to help finalize your preparation for your races, but it should not be used exclusively. Too much is gained from structured training on the road.
