So fast the heart should beat, As proud the heart with heavy feet.”
— Led Zeppelin’s Achilles’ Last Stand

Feel pain near the bottom of your calf or the back of your ankle? Achilles pain is a common occurrence for professionals and amateurs. The Achilles tendons are the tendons at the back of the ankle, connecting the calf muscle to the heel. If your Achilles is sore during or after riding you may have Achilles tendinitis or tendinosis. Inflammation, micro-tears or comprised blood flow, often caused by overuse, could put a stop to the riding season. Paying attention to your Achilles could help prevent the injuries that are common to cyclist.

Aside from bike fit, there is a whole host of stretching, strengthening, recovery and maintenance options available to athletes who are encountering Achilles issues. There are many excellent websites that show how to correctly stretch and strengthen this muscle group area. As always, if issues arise, I recommend first seeking medical advice from your personal physician or medical professional. They can identify what sort of injury you have, making sure you get appropriate treatment for your condition.

The muscles of the anterior compartment of the lower leg are generally responsible for dorsiflexion, and the muscles of the posterior compartment of the lower leg are generally responsible for plantar flexion. The lateral and medial muscles in both compartments invert, evert, and rotate the foot.

Proper pedal/cleat setup can help eliminate lower leg pain and help you increase your power on the bike. Generally, the ball of your foot should be directly over the pedal axle. While some cyclists find positioning the center of their cleat behind the ball of their foot (the bump on the inside of your foot behind the big toe) comfortable, others like to place the center of the pedal spindle even closer to the bump (behind the pinky toe) on the outside of the foot. If you feel strain in your calf, try moving your cleat slightly rearward on your shoe. Please be aware that this may require additional saddle height adjustment afterwards.

Second, consider more support inside your shoe. Over pronation, knees moving inward toward the top tube of the bicycle during the down stroke while pedaling, may attribute to Achilles pain. Often inexpensive insoles or the use of wedges in the shoe or between the cleat and shoe can help align the knee and foot lessening ankle rotation and lower leg stress. Finally, check for lateral rock in your bike shoes. When clipped into your pedals, see if someone can rock your foot side to side (like a boat on rough water). Replace all loose or worn cleats. Pronation in the foot can fatigue the calf and Achilles area.

Could saddle height contribute to Achilles issues? Maybe…A saddle set too high may force a cyclist to point the toes to reach the bottom of the pedal stroke. “Ankling”, otherwise known as excessive ankle movement or range, is often considered a culprit in AT pain. Similarly a low seat, high torque, heel down pedaling technique, as associated with seated hill climbing, may also cause issues.

Finally, cleat rotation is another thing to consider. While knees sometime enjoy increased float in the pedal, your Achilles may not. Increased float in your cleat and pedal system could promote AT problems. Pay special attention to your calves, ankles and AT when changing to a new pedal system or replacing cleats.

In the end, cyclists will greatly benefit from having a good bicycle position.. While considering these aforementioned ideas utilized in bicycle fitting, keep in mind, nothing beats a good bike fit from a well-trained and experienced fitter. Comfort and efficiency breed performance. Keep working at improving your position and ride more bike.

  1. Great advice! After a tour from a Paris to Brussels I am quite sore. My Achilles’ tendon is swollen! The unusual thing is that it’s just the Achilles on my left ankle.

    Since I am touring abroad with a rented bicycle I didn’t have proper cycling footwear, for the first 100mi I wore boots. I think because the ankle cuff of the boot “cradles” my AT, it aggrevates my AT more than if I had proper footwear. Still I am confused why the soreness and swelling is only on me left AT and not the other.

  4. Last year I rode Canada to Mexico and many short distance but never happened anything on my leg. Now l am officially riding Route 66 that this leg problem happened on my right leg at the 1st day. I am still at the beginning that makes my speed very low. 1st day l rode around 100 miles but 2nd day only 60 miles with that leg. I am wondering that should l keep cycling. I am just hoping that it will heal soon otherwise l won’t continue. There is not much pain but sometimes it hurts.

  5. Hi: I know the article is ancient, but I had to respond. I saw no mention of gearing in your exposition, but my experience with severe achilles tendinitis indicates that high ratios can cause or exacerbate achilles stress and tendinitis. Those who live among steep hills have trouble finding road bikes with low (reduction) gears; it’s often necessary to redo the cassette to be able to spin instead of grind up the hills.
    Achilles pain is one consequence; another is a loathing for hills that can be the best part of a ride.
    Think of gearing as another element of the “bicycle fit” equation.
    Just my 2 cents plain, from the steep, unglaciated part of Wisconsin…
