Base training is a traditional phase of cycling periodization and is utilized by coaches and athletes alike to prepare their bodies for the greater physiological demands the build and peak phases bring, increase sport specific strength, and improve pedaling technique; essentially you are training for the sake of training, not for a specific race or goal.

What is the Traditional way to Base Train?

Traditional base training involves doing a lot of long duration riding at low to moderate intensity with the goals of increasing capillary density, mitochondrial density, muscular endurance, and mental strength (pain tolerance).  This sounds great in theory, but is it just an archaic way of thinking and training?  Yes and no…Yes for the athletes who do not have 20+ hours per week to train and need to get a better return on their training time, and no for those athletes who have oodles of time to dedicate to their training.  Also, riding your bike for a long time at a slow pace (usually zone 2) will make you better at, you guessed it, riding your bike for a long time at a slow pace.  I don’t know about you, but I have never raced my bike slowly!  This does not mean that zone 2 training should be thrown out the window though…


So, if you don’t have hours and hours to train like a professional athlete, what should you do to increase your aerobic fitness?  That, my friends, is where Sweet Spot training comes in.

What is the Sweet Spot Zone?

The Sweet Spot zone is between 85-97% of your FTP, think high zone 3 and low zone 4…

This is called the Sweet Spot zone because it is smack dab in the middle of where you get the best bang for your buck in terms of return on training time invested.  You can spend a lot of quality time here without building up undue fatigue which allows for greater repeatability and increased training stress over the course of a training block.  Most importantly though, you can spend a lot less time in Sweet Spot compared to zone 2 training and get similar physiological improvements.  Thought of another way, espresso and coffee have a similar caffeine content, but you need a lot less espresso to achieve the same caffeine buzz.

Drawbacks of Sweet Spot Training

Refer back up to the physiological adaptations table, notice that Sweet Spot training does jack squat for your anaerobic system, neuromuscular power, and fast twitch muscle fibers?  This is a huge issue because athletes who specialize in road races, criteriums, cyclocross events, and track races rely heavily upon their anaerobic systems and fast twitch muscle fibers to generate breakaway power, power up a short and steep incline, accelerate after a sharp turn, and get off the blocks as quickly as possible.  So, make sure you are using the later stages of your off-season effectively and not just increasing your aerobic capacity if you plan on competing in any of these events!

Another drawback of Sweet Spot training is the ride lengths usually aren’t long enough for certain athletes.  For example, an athlete who specializes in road racing will typically spend 3 hours+ riding their bike during a typical road race, but if they are only spending 90 minutes on their bike at a time, even if they are working at a respectable intensity, chances are they will not have the muscular endurance or pain tolerance to last for 3+ hours and be able to produce a decent enough kick at the end to win.  So, make sure you are still getting out for those longer rides at least a couple times a month in the winter to maintain your muscular endurance and mental fortitude!

So, is traditional base training dead?  For all intents and purposes, yes!  Spending a lot of time on your bike at a low intensity will only make you better at riding slow for a long time, and secondarily will bore you to death.  As the winter closes in and your training time invariably decreases, don’t waste your time spinning aimlessly at zone 2!  Instead, include some Sweet Spot work into your routine and continue to watch your FTP and fitness rise steadily throughout the winter.  Remember to not just spin at Sweet Spot though as you will indubitably lose your anaerobic and neuromuscular power.  Finally, zone 2 still has it’s purpose!  It is beneficial for those athletes who are burnt out from a long season of racing, coming back after injury, or preparing their bodies for the high volumes and intensity of the build phase.  Don’t write off zone 2 entirely just yet…

  1. How much can one expect to improve (%) after say ten years of racing and training with the sweet spot method?

    Can you comment on weather it’s better to train for speed or increase your AT for shorter racing (not road racing)?

    Awesome article!!

    1. Hi TC, thank you for your question. There have not been any long-term studies conducted on SST training, but I assume it would be similar to traditional training (~5-10% increase of FTP per year), but it would take a lot less training time.

      I train my short distance athletes (track racers, criterium specialists, cyclocross athletes, etc.) for increasing anaerobic power and overall force. They will still do some SST work, but far less than my longer distance athletes.

      Thank you for reading 🙂
