It is a specific kind of internal torture. You spend a decade training your nervous system to fire in explosive, rhythmic bursts on a 400-meter synthetic loop, only to decide one day that you want to run 26.2 miles through the winding, often chilly streets of London. For london marathon track runners, the shift isn't just a change in scenery. It is a fundamental rewiring of what it means to be an athlete.
Honestly, the transition is brutal.
When people think of the London Marathon, they usually picture the masses in costume or the elite Kenyans floating over the pavement. But there is a subculture of "track refugees"—athletes who grew up on the cinder or Mondo tracks—who bring a very specific, high-cadence intensity to the Mall every April. These runners have the speed. They have the "kick." What they often lack, at least initially, is the skeletal durability to handle the relentless pounding of London's tarmac.
Why london marathon track runners struggle (and succeed)
The physics of a track are forgiving. Modern tracks are designed with a specific force reduction—essentially a tiny bit of "bounce" that saves your joints. London's roads? Not so much. When track specialists move to the marathon, they often deal with a "mechanical shock" that their bodies aren't used to.
Sir Mo Farah is the gold standard here. Think about it. He spent his life dominating the 5,000m and 10,000m. He knew exactly how many laps were left at any given moment. Then, he moved to the marathon. While he won Chicago and ran a blistering 2:05:11 in London in 2018, even a legend like Farah admitted the distance is a different beast entirely. On the track, you can "sit and kick." In London, if you wait for the final 400 meters to make your move, you’ve probably already lost the race at mile 19 near Canary Wharf.

Track runners have an incredible "economy." Their stride is usually more efficient than a lifelong road warrior. They don't waste energy. Every millimeter of movement is directed forward. This efficiency is why we see former track stars like Sifan Hassan—who won the 2023 London Marathon in spectacular, chaotic fashion—able to stop, stretch a cramping hip, and still hunt down the leaders. She brought a track runner’s "refuse to lose" mentality to a race that usually rewards patience over aggression.
The "Black Dog" of Mile 20
There is a psychological wall that hits track athletes differently. On a track, you have visual cues every 100 meters. You are never far from the finish line, even if you have twenty laps to go. The London Marathon course is a sprawling, psychological gauntlet.
Crossing Tower Bridge is iconic, sure. But once you turn right and head toward the Isle of Dogs, the crowds thin out slightly, the wind off the Thames bites, and the track runner's brain starts to scream. There are no bells to signify the final lap. There is just more road.
Training: From Spikes to Supershoes
Most london marathon track runners have to completely overhaul their gym routines. Track work builds fast-twitch fibers. Marathon work requires a conversion to slow-twitch dominance, or at least a very high oxidative capacity.

- Mileage Volatility: A 10k specialist might top out at 80–90 miles a week. A serious London contender is pushing 120+.
- The Taper: Track runners are used to "sharpening"—short, fast intervals before a meet. Marathoners have to learn the "taper craze," where they run less but feel like their legs are made of lead.
- Surface Variance: You'll see these runners trading the local athletics track for the towpaths of the River Lea or the hills of Richmond Park.
The Gear Shift: Carbon is King
You can't talk about modern road running without mentioning the shoes. For the track specialist, the transition has been made easier by "supershoes" like the Nike Alphafly or the Adidas Adios Pro. These shoes use PEBA-based foams and carbon plates to mimic the energy return of a track.
In the old days, running a marathon in racing flats felt like slapping the ground with pieces of cardboard. Now, track runners feel a familiar "pop" underfoot. This has arguably closed the gap between the disciplines. It’s why we see athletes like Eilish McColgan—who has a massive track pedigree—stepping up to the roads with such high expectations. The technology protects the calves and Achilles tendons, which are usually the first things to snap on a track athlete trying to go long.
Realities of the London Course
London isn't "flat and fast" in the way Berlin is. It has corners. It has cobbles (near the Tower). It has subtle elevation changes that can ruin your rhythm.
For someone used to a perfectly level 400m oval, the camber of the road in Woolwich or the narrow turns in Greenwich can be a nightmare. You have to learn to run "the line." Every extra meter you run on a curve is energy wasted. Elite track runners are masters of the inside rail; on the London course, that means hugging the blue line painted on the road with obsessive precision.

The Verdict on Track-to-Road Transitions
Is it worth it? Most say yes, eventually. The payday in road racing is significantly higher than on the Diamond League circuit. But the cost is paid in recovery. A track runner can race a 5,000m on Thursday and a 3,000m on Saturday. After the London Marathon, most pros won't run seriously for three weeks. Their muscles have literally undergone necrosis—cell death—from the eccentric loading of the downhill sections and the sheer duration of the effort.
It is a trade-off. You trade the precision and "pure speed" of the track for the grit and "glory" of the streets.
Your Actionable Roadmap for the Transition
If you are a track-focused runner looking to tackle London, don't just "go for a long run." You need a strategy that respects your speed while building your floor.
- Introduce "Grey Zone" Runs: Track runners love intervals (fast) and recovery (slow). You need to spend time in the "boring" middle—marathon pace. It will feel too slow at first. Do it anyway.
- Strengthen Your Soleus: Your lower calf takes the brunt of the road impact. Weighted calf raises are non-negotiable. If your soleus fails at mile 18, your race is over.
- Practice Fueling: You don't eat during a 1500m race. You must eat during a marathon. Start training your gut to handle 60–90g of carbohydrates per hour.
- Respect the Tarmac: Gradually move your sessions from the track to the road over a 12-week period. Do not make the switch in a single week, or you'll end up with stress reactions in your metatarsals.
- Study the Map: London is a tactical race. Know where the headwinds usually hit (the Highway) and where the crowd noise will spike your heart rate (Cutty Sark). Manage your adrenaline or you'll burn your matches before you even get to Westminster.
The transition from the oval to the streets of London is a journey from certainty to chaos. The track is controlled. London is a beautiful, loud, painful mess. Embrace the mess and your track speed will become your greatest weapon in the final mile down Birdcage Walk.
