A Cyclist's Guide to Fast Road Races

This is written as a guide for people with a strong cycling background — to help you run far and fast without major injury problems.

This guide stems from my own training experience combined with what I've learned as a competitive cyclist over many years, with Jon Åsbjørn Hauge (cycling coaching) as my coach. I've personally done countless of these exercises to get healthy legs, which were recently diagnosed with a stress reaction in the shinbone — a precursor to a stress fracture. I've likely had this since some marathon runs about 10 years ago, and have been running with pain ever since.

That includes when I ran a 10K road race in autumn 2023 in 31:24 at Under 10 for Grete, and a 5000m track race in 15:05 at Kvalheimmila at Bislett. What you'll find in this guide took me to those times, and onward on a journey toward injury-free running that I believe is extremely useful for all cyclists.

The Three Limiting Factors for Fast Running

We start from the premise that there are three decisive factors for fast running, important in this order:

Good fitness is the obvious winner, and this applies even when it's been developed through cycling, cross-country skiing, running, steep uphill walking, rowing, etc. High capacity lays the foundation for moving the body in all endurance sports.

Good Fitness and Well-Trained Legs

Most people know what good fitness is. For endurance athletes, it's characterized by measurable factors like high VO2max and high anaerobic threshold. Research shows that VO2max is the strongest predictor of endurance performance, and that aerobic capacity built through cycling transfers to running — although specificity matters.

If you're well-trained as a cyclist, you can run quite fast right away. It's great fun in those first sessions, but can quickly lead to injuries. Good technique and acclimatization are therefore extremely important.

It will take a long time before you're as good at running as at cycling. If you stop cycling to only run, you'll actually get in worse shape — because you can't activate the muscles and heart as much as on the bike. The body increases heart rate when it can't keep up, so even if HR goes up, it doesn't mean you're training optimally.

Train running uphill for good effect on fitness and capacity — it works better with a well-trained cycling musculature. In other words: keep cycling!

Good Running Technique — The Most Important Point

This is the single most important point in this guide. Dedicate yourself to good running technique if you want to run fast road races. Use this technique on all running sessions on gravel and asphalt.

Why? Good running technique allows you to run at high speed. For me, that's down to 3:00 min/km on 5000m, far faster than I'm comfortable with. If I were to train a lot at that pace for acclimatization, I'd get tired and struggle to complete the quality training. Only a few sessions before competition need elements of that speed.

Good running economy means the muscles work efficiently in running. It's the ability to run long without the muscles getting tired, tight, stiff, or sore — meaning they tolerate running well. This requires work over a long period and isn't something you can fix in a few weeks. In 3 months you can achieve a lot, and even more with 6 months.

Muscular Endurance and Running Economy

Running economy can be measured by a high aerobic and anaerobic threshold, but it's more than that. It's about the ability to maintain high speed without the muscles giving in — without the legs getting heavy, stiff, or sore.

For a cyclist, this is the biggest challenge. The cycling musculature is well-trained, but not adapted to the running motion. Building up takes time: patience is key. Increase training volume gradually and stick to good technique.

Use the training plan in this guide to build a solid foundation and running economy you can benefit from in road races. From this point you can see that we adopt good running technique from the very start — and with it we'll achieve good running economy. Then we have the fitness from cycling, the stride to run fast, and the economy to run far.

VO2max and Race Times — What Your Cycling Fitness Is Worth

In the book 4x4 by Helgerud and Hoff, a table of estimated race times based on VO2max is provided. For cyclists, it's useful to see what your aerobic capacity — which you may know from cycling training — translates to in running times. Here's an overview with corresponding watts/kg for cyclists:

The table shows that a cyclist with good fitness (e.g., ~5 W/kg FTP, VO2max around 70) has the physiological capacity to run 10K in about 31 minutes — but it requires good running technique and muscular adaptation to realize this potential.

Strength and Injury Prevention

From our perspective, very little strength training is necessary if you run with good technique. However, there are some exercises that can be done very time-efficiently with good effect.

Training Plan for Cyclists Who Want to Run Fast

Starting from the premise that cycling is maintained to keep fitness up and the body injury-free. Include foundation training in the program — cyclists have a weak foundation for running.

It's in competition that it counts. The PR you set in a road race stands forever. Train smart over weeks and months, build a foundation with the technique and training tips here. Aim for a road race, peak your fitness, and shock your local running community with a massive performance.

The Recipe for Fast Road Races

The recipe is simple — but it requires patience and dedication to technique from day one:

With this approach, you can leverage the aerobic capacity you've built as a cyclist and translate it into impressive running times. Good fitness, good running stride, and patient build-up — that's all it takes.
