Getting faster on a bike comes down to a handful of levers: how you train, how you position your body, how you fuel, how you recover, and how strong you are off the bike. Most cyclists leave significant speed on the table in at least one of these areas. The good news is that even small, targeted changes can produce measurable gains.
Structure Your Training Around Intensity
Riding more miles at the same comfortable pace is the most common plateau trap in cycling. To get faster, you need to deliberately vary how hard you ride, and the best framework for doing that is power-based training zones. These zones are pegged to your Functional Threshold Power (FTP), the highest average power you can sustain for roughly an hour. Zone 1 (active recovery) sits below 55% of FTP, Zone 2 (endurance) runs from 56 to 75%, Zone 3 (tempo) covers 76 to 90%, Zone 4 (lactate threshold) is 91 to 105%, and Zone 5 (VO2 max efforts) spans 106 to 120%. Above that are short, explosive efforts in the anaerobic and neuromuscular ranges.
If you don’t have a power meter, you can estimate zones by heart rate or perceived effort, but power provides the most consistent feedback because it doesn’t drift with fatigue, heat, or caffeine.
Why Polarized Training Works
The training distribution that consistently produces the best results for cyclists is called polarized training. The concept is straightforward: spend the large majority of your riding time at low intensity (Zones 1 and 2), and concentrate your hard efforts well above your lactate threshold, at intensities exceeding 80% of your maximum aerobic power. You deliberately avoid spending too much time in the moderate “gray zone” (Zone 3), where the effort feels productive but doesn’t generate the same adaptations.
Research published in the International Journal of Environmental Research and Public Health found that polarized training produced the best results for developing peak oxygen uptake, peak power, and time to exhaustion compared to other training strategies. Trained cyclists in polarized programs showed greater improvements in peak power output, lactate threshold, and high-intensity exercise capacity. Recreational athletes saw similar benefits, including faster race times and bigger jumps in VO2 max.
A practical starting point: aim for roughly 80% of your weekly training time in Zones 1 and 2, and 20% in Zones 4 and above. That might look like three or four easy endurance rides and two structured interval sessions per week. The easy rides should feel genuinely easy, conversational pace. The hard sessions should be uncomfortable enough that you couldn’t sustain them for long.
Dial In Your Interval Sessions
The quality of your hard days matters more than the quantity. Here are three interval formats that target different systems, and all of them will make you faster:
- Threshold intervals: 2 to 4 efforts of 8 to 20 minutes at 91 to 105% of FTP, with 5 to 10 minutes of easy spinning between each. These build your ability to sustain a high pace for long periods.
- VO2 max intervals: 4 to 6 efforts of 3 to 5 minutes at 106 to 120% of FTP, with equal rest. These push your aerobic ceiling higher.
- Short, explosive repeats: 8 to 12 efforts of 30 seconds to 1 minute at maximum intensity, with 2 to 4 minutes of recovery. These develop your ability to respond to surges, attacks, and short climbs.
Pick one or two of these per week. Don’t stack hard days back to back. The adaptation happens during recovery, not during the effort itself.
Find Free Speed With Aerodynamics
At speeds above about 25 km/h, air resistance is the dominant force slowing you down, and it increases with the cube of your speed. That means small changes to your body position can save a surprising amount of power. Testing by SILCA found that simply moving from riding on the hoods to the drops saved nearly 20 watts at 40 km/h (about 25 mph). Bolting on clip-on aerobars and tucking into them saved a remarkable 62 watts at the same speed.
You don’t need to buy new equipment to benefit. Lowering your torso by bending your elbows more, narrowing your shoulder profile, and keeping your head down when pushing hard are all free. On flat roads and descents, riding in the drops is one of the simplest ways to go faster without any extra fitness. If your bike fit allows it, practice spending more time in a lower position until it becomes comfortable.
Clothing matters too. A tight-fitting jersey creates noticeably less drag than a loose one, and shoe covers smooth out the turbulence around your feet. These gains compound over the course of a ride.
Optimize Your Cadence
There’s no single “best” cadence for all situations. Research on track cyclists found that the cadence producing the most power for the least metabolic cost shifts upward as intensity increases. At lower aerobic intensities, the sweet spot is around 66 rpm. At the effort level where your body is burning the most fat, it rises to about 76 rpm. At your lactate threshold, it’s roughly 82 rpm, and at VO2 max effort, it climbs to around 84 rpm.
The practical takeaway: if you’re grinding along at 60 rpm on a flat road, you’re probably pedaling too slowly for the intensity. Most experienced cyclists settle between 80 and 95 rpm for sustained efforts. Shifting to a slightly easier gear and spinning faster reduces the force per pedal stroke, which delays muscular fatigue. Experiment during your endurance rides. If your legs burn out before your lungs do, try increasing your cadence by 5 to 10 rpm.
Fuel Your Rides Properly
Underfueling is one of the most common and fixable reasons cyclists slow down in the second half of a ride. Your body stores enough glycogen for roughly 90 minutes of hard effort. After that, you need to replace carbohydrates or your power output drops sharply.
For rides lasting two to three hours, aim for about 60 grams of carbohydrates per hour. This is roughly the maximum rate your gut can absorb from a single carbohydrate source (like glucose or maltodextrin alone). For longer events, you can push intake up to around 90 grams per hour by using a mix of glucose and fructose in a 2:1 ratio, which uses two different absorption pathways in the gut. Some trained cyclists in mountain bike races consumed as much as 95 grams per hour using these dual-source formulas.
In practical terms, 60 grams per hour is about two energy gels, one large banana plus a sports drink, or a bottle of well-mixed carbohydrate drink. Start fueling within the first 30 to 45 minutes of your ride, not when you’re already feeling flat. Your gut can be trained to tolerate higher carbohydrate loads, so practice your fueling strategy on training rides before using it in an event.
Add Strength Training Off the Bike
Heavy resistance training improves cycling performance in ways that more riding alone cannot. Studies show that adding a structured strength program increased peak power output by roughly 9% in male cyclists and nearly 13% in female cyclists. Both men and women also showed improved cycling economy during longer efforts, meaning they used less oxygen to produce the same power output. In plain terms, the same pace felt easier.
The most effective exercises target the primary cycling muscles: squats, deadlifts, leg presses, and single-leg movements like lunges and step-ups. Two sessions per week is enough. Focus on heavy loads (3 to 6 reps) rather than high-rep endurance sets, since the goal is to build force production, not muscular endurance, which you already develop on the bike. Keep the sessions short and schedule them on easy ride days or rest days so they don’t compromise your key interval workouts.
Prioritize Sleep and Recovery
Sleep is where your body consolidates the fitness gains from training. Cutting it short doesn’t just make you feel tired, it measurably reduces your performance. Research on cyclists found that after a night of restricted sleep, maximum work rate dropped by 15 watts during a 30-minute effort at 75% of peak power. VO2 max also decreased, meaning the aerobic engine itself was impaired. Perhaps most importantly, perceived effort spiked, so the same pace felt significantly harder, which led to faster exhaustion and longer completion times in testing.
Most endurance athletes need seven to nine hours of sleep per night to fully recover between hard training sessions. If you’re adding intensity to your program, you may need more than you did before. Consistent sleep and wake times, a cool and dark bedroom, and limiting screens before bed all improve sleep quality. Naps of 20 to 30 minutes can partially offset a rough night, but they don’t replace consistently good sleep over time.
Beyond sleep, managing the stress of your overall training load matters. Easy days need to be genuinely easy. If you find yourself unable to hit your target numbers on interval days, or if your resting heart rate is creeping up over several days, you likely need more recovery, not more training.
