Coach’s Column – Start Fast and Win at Your Next Ultra Endurance Race

Question: I plan on adding a few ultra-endurance races to my calendar this year – two 100 milers and a 100k race.  I have only raced XC races as a Cat 1 racer.  I have heard that many of the endurance races start fast to get good position in early singletrack.  How do I work on my pacing to have a podium finish in the ultra-endurance races?

 

Answer: 100 km and 100-mile mountain bike races do start fast! To achieve your goal of a podium placement you do need to be able to start at a pace higher than is sustainable then be able to recover and continue at a sustainable race pace. It is exactly the same scenario as a cross-country race, just with the need to keep going longer after the fast start. This means you cannot dig as deep in an endurance race as a cross-country race at the start. Pacing is crucial.

Course design will dictate the optimal start strategy. In order to burn energy riding over a sustainable pace there must be a significant pay-back for that energy investment. Getting through an early bottleneck in front of a traffic jam is one significant reason. Staying with the lead pack and drafting on a long open section is another strategy that will give you a positive return on your investment.

Training:

From cross-country racing you will already have good VO2max and threshold power and know how to start a race fast. First, what you need to add into your training is longer rides at an aerobic base pace of 56-86% of threshold power or heart rate zones 2-3 and then second, longer rides at race pace. Start with a 4 hour ride at aerobic base pace on the weekend while maintaining your typical cross-country training routine of race start practice, sprints, VO2max and threshold power work during the week. After getting a couple of 4-hour aerobic base pace rides under your belt, increase the pace of these longer rides and reduce your cross-country specific training to avoid becoming over-trained. A key training session is to warm up, ride a 4-6 minute VO2max pace effort, then drop into 100 miler race pace of 56 – 90% of threshold power. End this ride with a threshold power interval. If you have the energy left at the end of a 4 to 6 hour ride to put in an 8 to 10-minute effort at threshold power, you are race-ready for your podium hundie.

Pacing on race day:

Your goal at the start of an endurance race is to maximize strategic advantages and minimize the amount of time spent pacing above your sustainable race pace of 56-90% of threshold power. Every minute spent above 90% of threshold power at the start, reduces the opportunity for a strong finish. Ideally, stage as near to the front as possible and draft off the leaders for as long as possible. Save energy wherever you can. The length of time you should spend above 90% threshold power depends on your recent training, fatigue levels and personal abilities. It is never limited by motivation at the start of the race so watch your power meter and keep a lid on it! Pacing above 90% of threshold power at the start of a race when motivation is high and legs are fresh will feel easy so don’t trust your perceived exertion. Keep the amount of time above 90% of threshold power to less than 5 minutes in the first 30 minutes of the race. Spend this time wisely by ensuring you have a good return on your investment and are pedaling this hard for a tactical gain.

Once you have made it through the first course bottleneck or made the selection for the lead pack, settle into your race pace and focus on calorie, electrolyte and fluid intake to keep energy levels high. Keep cadence on the high side of your comfortable range in the first half of the race to put the work on your cardiovascular system and save your muscles for the second half for the race. Always save a little in reserve for a strong finish.

Coach’s Column – Boost Your Fitness with a Power Meter

Question: In your last column, you gave advice on buying a power meter to use for training on the mountain bike as well as how to set up training zones.  Is training with a power meter similar to training with a heart rate monitor?  What are your favorite workouts using the power meter for your average cross country racer?  Does heart rate still factor into the training?
Answer:

Is Training with a Power Meter Similar to Training with a Heart Rate Monitor?

Training changes significantly on both the micro and macro level once an athlete has switched over from using heart rate as their primary training metric, to power. Power is a direct measure of exercise whereas heart rate is a response to exercise plus many other factors such as fatigue, dehydration, heat, adrenaline, caffeine, altitude and more. These “other” factors make interpreting heart rate data and creating training decisions based on it complicated and rife with guessing. Training with power is clear, precise and has no guessing. You put the power into the pedals and produce the work or you do not. You hit the power target and workout goal or go home to bank recovery. It is an easy decision leading to accurate training.

Many top pros incorporate power training into their training plans. Alex Grant's team Scalpel with SRM power meter just before the 2015 world championships.

What are Your Favorite Workouts Using the Power Meter for Your Average Cross Country Racer?

The classic workouts that produce fast cross country racing are still my favorite. The difference when training with power is in the accurate pacing and execution of each workout.

10 x 1 min at power L6 with 3 min recovery

6 x 3 mins in power L5 with 3 min recovery

3 x 20 min off-road at cross country race pace with 10 min recovery

Pacing intervals with power vs heart rate:

The biggest difference when pacing intervals, is the lack of time-lag with power that is present with heart rate. Power feedback is immediate. Heart rate feedback has a time-lag. When pacing intervals with power, at the start of each interval, an athlete can dial up immediately to the target power and maintain it for the duration of the interval. When training with heart rate there is a time-lag of 30 – 45 seconds between putting power to the pedals and heart rate rising into the target zone. This time-lag duration leaves you guessing how hard to pedal until heart rate rises and settles into the target zone. Training with heart rate often encourages over-powering the beginning of intervals when trying to get heart rate up quickly into the target zone. Overshooting the target heart rate after starting too quickly leads to under-pacing the end of an interval in order to get the heart rate back down into the target range. The net is a large proportion of the interval duration is spent outside the target range. Training with power takes the guesswork out of pacing intervals and increases the pedaling time on target, increasing training quality. Training with power is like hitting the bullseye every time.

1 minute intervals:

For intervals less than one minute in duration, heart rate does not have time to respond, resulting in both a lack of pacing accuracy and training data to be analyzed. Pacing intervals of less than one minute with power is accurate and produces valuable data to analyze and compare future and past workouts with.

Training with heart rate and fatigue:

Fatigue will depress heart rate. Endurance MTB racers will at times be training while fatigued due to the combination of speed training and long endurance sessions needed to be a successful MTB endurance racer. An athlete can be tricked into training too hard when trying to push a depressed heart rate up into a target training zone. This can lead to over-training. Training with power will increase pacing accuracy producing better results and reducing the risk of over-pacing and over-training.

Track and analyze your season:

One of the most powerful uses of a power meter is to track total training load for both a single workout and over time using the training stress score (TSS) metric generated with power data. TSS takes into account both exercise intensity and duration.

A single ride TSS is like looking at a single tree in a forest. You get a nice picture of that tree but don’t know where it sits in the forest. That is where the Performance Manager Chart (PMC) comes in. The PMC tallies up TSS over time using an exponentially weighted rolling average to give a bird’s eye view of the forest – or your entire season. The PMC can be used retroactively to look at data during times you had personal best performances and during times you thought you should have but didn’t. It can be used for forward planning to target peak form and to perfect peak timing to nail the race of your life.

 

Does Heart Rate Still Factor Into the Training?

Yes, absolutely, heart rate is still a valuable metric to track. Comparing power and heart rate is useful to gauge the physiological strain of a workout and the depth of fatigue an athlete is carrying. It can also pinpoint dehydration when a rising heart rate is seen with decreasing power during a long ride or race. Resting heart rate and heart rate variability (HRV) are two useful heart rate metrics to track health and training readiness.

Heart rate variability:

Tracking Heart rate variability (HRV) is a valuable use of heart rate data to assess the status of an athlete and their training readiness. More info on HRV tracking here.

Training with power data is a real advantage over heart rate only. Training with both heart rate and power data tracking capabilities is optimal to get a complete picture to work with.

Coach’s Column – MTB Training with Power

Question: I want to start training and racing with a power meter on my mountain bike.  What do you recommend for a power meter and how do I establish my training zones using the power meter?  Will I need a separate power meter for my road bike if I train on both, especially since my road bike will be my ‘trainer bike’ for the winter?

Answer: Planning and pacing your training with a power meter is a huge advantage. There are many power meters on the market. Read through DC Rainmakers 2015 power meter buyers guide for a detailed review of every known option. Not all of these power meters work for mountain bikes due to compatibility or durability issues. We need a power meter that can take a beating. The most popular mountain bike power meters with proven durability off-road are Stages, PowerTap Hub, SRM and Power2Max. One of the new products on the market is the 4iiii’s power meter however they currently support aluminum cranks only so anybody with carbon cranks is out of luck.

It is possible to have one power meter that you move back and forth between bikes but it is inconvenient to switch these often. The power meters are located in the crank arms (Stages, SRM and Power2Max) or rear wheel (PowerTap hub). If these parts are compatible between your MTB and road bike you can do the switch with a little wrenching to change the crank or rear wheel.

If you are adding a power meter to only one bike, the bike to choose is the one you ride the most. This will maximize the use you get out of the power meter. If this is equal, put it on your mountain bike. The best option is to have a power meter on every bike.

Once you have your power meter installed, read the manual to understand the calibration and zeroing requirements. Some power meters will auto zero and/or calibrate and others you need to do manually before each ride to maintain accuracy.

To establish your power training levels, warm up very well then do a 20 min all-out, non-stop time trial effort on a flat road or up a continuous gradual climb. Enter your average 20 min power from this time trial to our LW Coaching Power Level and Heart Rate Training Zone Calculator to calculate your power training levels.

Now you are ready to start pedaling in watts and producing TSS (Training Stress Score).

Coaching Column with Alison Dunlap: What Age Should Children Start Training?

Question: At what age do you think it’s ok to start really structured training and racing?  What would you focus on for a young teenager or pre-teen?

Answer: Cycling is a challenging sport as we all know.  The emphasis with young kids should be on the pure joy of riding and the fun that can be had cruising up and down the alleys around your neighborhood.  Go on an “urban assault” with your kids and show them all of the obstacles that can be ridden on a bike.  During these younger years it is important that kids be exposed to many kinds of activities, not just cycling.  This will help develop coordination, balance, movement and cognitive skills.  The emphasis should not be on structure, but the fun and enjoyment of being active with friends and family.  It is not appropriate to ask a young child (pre-puberty) to “train”.  Kids at this age should be allowed to play for the sake of enjoyment and not have to follow the rules and regimens of adult level sport rules. [1]

Once a child reaches puberty she can start engaging in more specialized opportunities with an emphasis on organized and personalized training.   Kids should learn how to train properly in this phase with the focus on development, not outcome.[2]   Competition can be introduced but it is not the main objective.  A child’s love of sport and her internal motivation to participate become stronger and more developed during this phase.   Help your child experience the joy and fun of cycling while giving them a healthy understanding of how to train.

Make cycling a social activity.  Friends are everything to kids at this age.   Remember it is all about the process, not the results.  You are trying to develop a lifelong love of the sport that will keep your child active well into her adult years.

The amount of time spent in this development stage isn’t determined by a specific age.  It will vary with every child and depends on maturity and interest level.[3]  Kids that fail to develop a strong intrinsic drive during this time period will usually quit the sport before reaching the elite ranks.  So don’t rush it or convince your child he/she may be the next cycling superstar at the ripe age of 17.

We want our children to love to ride.  And we want them to carry that passion with them until they are too old to get out of bed.
