4-Week Road Cycling Training Plan to Boost Your Average Speed

You’ve probably felt that sting of watching your speedometer creep up just a few meters per hour while the world whizzes by. Whether you’re chasing a personal best, trying to keep up with a group, or simply want to feel the wind on your face a little faster, a focused four‑week plan can make a real difference. I’ve tried dozens of tweaks on my own rides, and the one that stuck was a blend of short, sharp intervals and steady endurance rides. Below is the plan that helped me shave 2 km/h off my average on a 120‑km weekend ride, and it’s simple enough for most riders to follow.

Why Speed Isn’t Just About Power

Before we dive into the schedule, let’s clear up a common myth: more power doesn’t always equal more speed. Aerodynamics, cadence (how fast you spin the pedals), and how efficiently you use your energy matter just as much. Think of it like a car: a big engine helps, but if the shape is boxy you’ll still be fighting wind. In cycling, a smooth pedal stroke and a relaxed position can give you the same boost as a few extra watts.

How the Plan Works

The four weeks are built around three pillars:

Interval work – short bursts that push your heart and legs, raising your FTP (Functional Threshold Power, the highest power you can hold for about an hour).
Endurance rides – longer, steady rides that teach your body to burn fat and spare glycogen, keeping you fresh for the hard bits.
Recovery – easy days that let the body adapt without adding fatigue.

Each week has a “hard day,” a “medium day,” a “long day,” and two easy days. The fifth day is optional; you can use it for a skill session, a group ride, or just a relaxed spin.

Week‑by‑Week Breakdown

Week 1 – Building the Base

Day	Workout	Why it matters
Monday	Rest – 30 min easy spin if you feel stiff	Gives muscles a chance to repair
Tuesday	Intervals – 5 × 3 min at 110 % of FTP, 3 min easy spin between	Raises your VO₂ max (how fast you can use oxygen)
Wednesday	Recovery – 45 min at 50 % of FTP, high cadence (90‑100 rpm)	Improves pedal smoothness
Thursday	Tempo – 2 × 20 min at 85 % of FTP, 5 min easy spin between	Teaches you to hold a strong pace for longer
Friday	Rest – optional short spin	Keeps you fresh for the weekend
Saturday	Long Endurance – 3 h at 70 % of FTP, keep cadence around 80 rpm	Builds aerobic engine
Sunday	Skill/Group Ride – 1‑2 h easy, focus on cornering or drafting	Makes you a better, safer rider

Tip: Keep a log of your power numbers. If you don’t have a power meter, use heart rate zones as a guide: intervals should feel “hard but sustainable,” tempo rides “comfortably hard.”

Week 2 – Adding Speed Work

Day	Workout
Monday	Rest or 30 min easy spin
Tuesday	VO₂ Max Intervals – 6 × 2 min at 120 % of FTP, 2 min easy spin
Wednesday	Recovery – 1 h at 55 % FTP, focus on smooth pedal stroke
Thursday	Sweet Spot – 2 × 15 min at 95 % FTP, 5 min easy spin
Friday	Rest
Saturday	Endurance + Sprint – 2 h at 70 % FTP, finish with 6 × 15 sec all‑out sprints, 2 min easy spin
Sunday	Group ride or skill session, keep effort easy

Why the sprints? Short, max‑effort bursts train your fast‑twitch muscle fibers, which help you accelerate out of corners and on flat stretches. They also improve your neuromuscular coordination, meaning your legs learn to fire in perfect sync.

Week 3 – Sharpening the Edge

Day	Workout
Monday	Rest
Tuesday	Threshold Intervals – 3 × 12 min at 100 % FTP, 6 min easy spin
Wednesday	Recovery – 45 min at 50 % FTP, high cadence
Thursday	Mixed Intervals – 4 × 4 min at 105 % FTP, 2 min easy spin
Friday	Rest
Saturday	Long Ride with Tempo Blocks – 4 h at 70 % FTP, include 2 × 20 min at 85 % FTP in the middle
Sunday	Easy spin or skill work, 1 h

Note: The threshold intervals are the real test of your stamina. If you can hold the power for the full 12 minutes, you’re likely to see a jump in your average speed on longer rides.

Week 4 – Taper and Test

Day	Workout
Monday	Rest
Tuesday	Short Intervals – 8 × 30 sec at 130 % FTP, 2 min easy spin
Wednesday	Recovery – 30 min at 50 % FTP
Thursday	Race‑pace Simulation – 2 × 20 min at 95‑100 % FTP, 10 min easy spin
Friday	Rest
Saturday	Test Ride – 120 km at a steady pace, try to hold the speed you’ve been aiming for
Sunday	Light spin, celebrate the work you’ve done

During the final week you’ll notice the volume drops but the intensity stays high. This “taper” lets your body stay sharp while shedding any lingering fatigue, so you’re ready to show off the new speed on Saturday’s test ride.

How to Track Progress

Average Speed – Use your bike computer or phone app to note the speed on the test ride. Compare it to a similar ride you did before the plan.
Power or Heart Rate – If you have a power meter, look for a higher FTP number after week 3. If not, a lower heart rate at the same effort is a good sign.
Feeling – Do you feel steadier on climbs? Is it easier to keep a high cadence on flats? Those subjective cues matter as much as numbers.

My Personal Story

I tried a version of this plan last spring on a 150‑km loop around the Hudson Valley. The first week felt brutal; my legs were screaming after the Tuesday intervals. By the third week, I could hold a 28 km/h average on the rolling hills without feeling wiped out. The real kicker was the Saturday sprint set on week 2 – I was laughing at myself, trying to “fly” off a short straightaway, and my friends on the group ride shouted, “Jordan, you’re a rocket!” That burst of confidence carried over to the final test ride, where I finally broke the 30 km/h barrier on a mixed‑terrain course. It wasn’t just the power; it was the smoother pedal stroke and the mental habit of pushing hard for short periods that made the difference.

Tips for Success

Stay hydrated and fuel smart. A 60‑gram carbohydrate snack every hour on long rides keeps glycogen stores topped up.
Check your bike fit. A cramped position wastes energy; a relaxed, aerodynamic posture lets you stay fast longer.
Sleep. Aim for 7‑9 hours; recovery happens mostly while you’re asleep.
Listen to your body. If you feel persistent pain, back off a day or two. The plan is a guide, not a rulebook.

Give this four‑week schedule a go, and you’ll likely see a noticeable jump in your average speed. Remember, the goal isn’t to become a pro overnight but to build habits that keep you faster, stronger, and more confident on the road. Pedal hard, stay safe, and enjoy the ride.
