How to plan a 200 km ride (and finish it)

Two hundred kilometres is not a long ride with extra kilometres bolted on. It's a different problem. Somewhere past the five-hour mark the limiting factor stops being your fitness and becomes your fuelling, your pacing discipline and your willingness to keep turning the pedals while your body suggests otherwise.

The good news is that almost all of it can be planned in advance, on a kitchen table, with a map and some arithmetic. This is that arithmetic: what intensity to hold, how much to eat and drink per hour, where to put the climbs and the shops, and what to expect in your own head at 150 km.

Pacing: a fraction of FTP, not a feeling

The single most common way to fail a 200 km ride is to ride the first 60 km at the pace of a good 100 km ride. Fresh legs lie. The number that keeps you honest is your FTP — and for a full day out, the target sits a long way below it.

There's a second reason to be conservative, and it's well documented: the power you can hold at a given physiological cost deteriorates as the ride goes on. Researchers call this durability, and it means the effort that felt like 65% of FTP at hour one is genuinely harder at hour seven, for the same watts. Plan for the rider you'll be at kilometre 160, not the one at the start line.

The fuelling arithmetic

Here is the number that decides most 200 km rides: 60–90 g of carbohydrate per hour. The upper end of that range depends on using a mix of glucose and fructose, because the gut absorbs them by different routes and the combined ceiling is higher than glucose alone can reach. Over eight hours that's somewhere between 480 and 720 g of carbohydrate — roughly 10 to 15 gels' worth, except that nobody should attempt a day like this on gels alone.

Two practical consequences. First, you cannot carry it all. A 200 km ride is a resupply plan with a bike ride attached. Second, your gut needs practice. Tolerance for high carbohydrate intake is trainable — riders who habitually take 90 g/h do so because they built up to it in training, not because they're lucky. Trying it for the first time on the day is how you end up sitting on a verge at kilometre 140.

An hour-by-hour template

This is a skeleton, not a script. Adjust the fluid volumes hard for heat: sweat rates in endurance athletes commonly sit above a litre an hour and go well beyond that in the heat, which is exactly why any single recommended number is wrong for somebody.

Water, salt and where the taps are

Fluid is the part riders plan worst, because it's heavy and bottles are finite. Two large bottles is roughly 1.5 litres — one to two hours of riding in warm weather, and less than that if you're a heavy sweater. On a 200 km route in summer you will need four to six refills, and they need to be identified before you leave, not discovered.

• Map the water first, then the food. Cemeteries, municipal fountains, graveyard taps and petrol stations are more reliable than village shops, which close.
• Assume one stop will fail. The shop shuts on Sundays; the fountain is dry. Every plan needs a fallback within about 20 km.
• Carry some sodium. Over many hours of sweating, drinking plain water in large volumes without replacing sodium is the route to exercise-associated hyponatremia — rare, but genuinely dangerous, and more likely on slow, hot, long days than on fast short ones.
• Drink to a plan, then to thirst. The consensus advice is to avoid losing more than about 2% of body mass to dehydration, and equally to avoid drinking so much that you gain weight over the ride.

If a café stop is part of the day — and on a good 200 it should be — Moveee's coffee-stop finder will show what's actually on the line of the route rather than 4 km down a valley you'd have to climb back out of.

Where to put the climbs

This part is craft, not science, but it's consistent enough to be worth stating plainly: front-load the climbing, but not the first hour. The pattern that works, ride after ride, is a gentle opening hour, the serious vertical metres between hours two and five while you're fed and fresh, and a final third that's flat, rolling or downhill.

• Avoid a sting in the tail. A 6 km climb at kilometre 185 will define the whole day in your memory, and not kindly.
• Put the resupply before the climb, not after. Arriving at a long ascent with full bottles and 60 g of carbohydrate on board changes everything.
• Check the prevailing wind. A loop that climbs into a headwind in the morning and returns with a tailwind is a materially easier day than the same loop ridden backwards — see reading the wind forecast.
• Watch the total vertical, not just the distance. 200 km with 1,000 m of climbing and 200 km with 3,500 m are different events by two or three hours.

If you'd rather not draw it by hand, Moveee's Route builder gives you the elevation profile and surface breakdown as you draw, and exports a GPX when you're happy with it.

The mental splits

Two hundred kilometres is too big a number to hold in your head for eight hours. Everyone who finishes these regularly breaks the day into pieces, and the pieces are remarkably similar from rider to rider.

Building up to it

You don't need to have ridden 200 km to ride 200 km, but you do need a long ride habit. A reasonable progression is a weekly long ride that reaches around 140–160 km three or four weeks before the target, then backs off. What matters more than the single longest ride is the accumulation of time in the saddle, and having practised the fuelling at full rate on at least two of those rides.

If you'd rather the build-up were planned for you, an adaptive plan handles the same logic — the long ride grows week by week, the hard days ease when you've genuinely emptied yourself, and the taper happens on purpose rather than by accident. The same progression that gets riders to a first 100 km scales up; it just takes longer.
