Ford RideLondon-Essex 100: Training Guide
A fast, flat-ish closed-road century where the real skill is holding a group and pacing your time goal.
RideLondon-Essex 100 is one of the UK's flagship mass-participation rides: roughly 100 miles on fully closed roads, starting in central London and looping out through the Essex countryside before returning to the capital. Unlike a mountainous sportive, the challenge here is rarely a single climb. It is the combination of distance, a steady undulating profile, and the strange dynamics of riding among thousands of other cyclists on car-free roads.
Most riders come in with a time goal — under six hours, under five, or simply to finish strong — and the closed roads make those targets genuinely achievable if you pace well and use the groups. The flip side is that the day rewards riders who can sit in a bunch, hold a wheel safely, and resist the temptation to chase every surge. This guide focuses on building the sustained aerobic endurance and group-riding composure the event actually demands. Treat all distances and elevation figures as approximate and confirm the current route on the official site.
What makes it hard
- Sustained tempo, not survival. The profile is rolling rather than savage, so there is no enforced recovery on long descents. You can ride at a steady, fairly high effort for hours, which quietly drains you if you started too hard.
- Group dynamics. Closed roads mean huge, fast-moving bunches. Drafting saves enormous energy, but surges, braking, and nervous riders punish anyone who can't hold a wheel or read the pack.
- Pacing to a time goal. The flat course tempts riders to push early when fresh. Going out too hard in the first 30-40 miles is the classic RideLondon mistake, and the back half is where it shows.
- Fuelling at speed. Four to six hours of steady effort burns a lot. Eating and drinking consistently while riding in a moving group takes practice most riders skip.
- Late-ride sharp efforts. Short rises, roundabouts, and any headwind sections near the finish can fragment groups, forcing repeated accelerations exactly when your legs are emptiest.
The course and what to expect
The route runs out of central London and into Essex on closed roads, returning toward the capital for the finish. The terrain is best described as rolling to gently undulating: plenty of short rises and false flats, but no sustained mountain climbs. That makes average speeds high and means you will spend most of the day in or near large groups. Exact mileage and the precise course vary year to year, so check the official route map before you build your plan.
Because the roads are closed, the experience is closer to a road race than a typical sportive. Bunches form quickly, ride fast on the flatter sections, and string out on the rises. Wind direction across the open Essex farmland is often the deciding factor in how hard the day feels — a tailwind out and headwind home, or vice versa, completely changes your pacing maths. Plan to ride conservatively early and keep something for the final stretch back into London.
Building the engine
The fitness you need is classic road endurance: the ability to hold a steady tempo for four to six hours without fading. Your weekly long ride is the cornerstone. Build it progressively until you can comfortably ride at least 70-80 miles at a controlled pace, ideally including some efforts at the kind of sustained tempo you'll hold on the day rather than only easy spinning.
Add one or two structured midweek sessions to raise your threshold and your ability to recover from repeated efforts — sweet-spot intervals (long blocks just below threshold) translate directly to holding a fast group. Because the course is flat, do not neglect your ability to produce repeated short surges; the accelerations out of roundabouts and over rises are what drop people. A few sets of one-to-three-minute efforts each week keep those top-end gears available when groups split late.
Group riding and pacing strategy
If you take one thing from your preparation, make it group-riding competence. Practise sitting in a bunch, holding a wheel a safe distance back, pointing out hazards, and rolling through turns smoothly. The energy you save by drafting is the single biggest lever on your finishing time — riders of equal fitness can finish 30-45 minutes apart purely on how well they use the groups. Find a local club run before the event if you can.
For pacing, decide your target and work backwards into an average speed and effort, then deliberately ride the first third below that. The closed roads and fresh legs make early restraint feel almost silly — do it anyway. Aim to fuel from the very start: a target of roughly 60-90 grams of carbohydrate per hour suits most riders for an effort this long, taken little and often so you never bonk in the back half. Know where the official feed stations sit and treat them as planned stops, not emergencies.

Common questions
How fit do I need to be to finish?
If you can comfortably ride 70-80 miles at a steady pace, you can finish. The closed roads and helpful groups make 100 miles more manageable than the same distance solo. Build your long ride progressively over a few months.
What time should I target?
Many recreational riders finish in roughly six to eight hours including stops; fitter riders using groups well aim for five hours or under moving time. Set a realistic target from your training data and pace the first third conservatively.
Do I really need to practise group riding?
Yes. The bunches are large and fast, and drafting saves more energy than any amount of extra fitness. A few club runs beforehand to learn to hold a wheel and roll through safely will pay off more than another interval session.
How much should I eat and drink?
Aim for roughly 60-90 grams of carbohydrate per hour, taken little and often from the start, plus steady fluids. Use the official feed stations as planned stops and rehearse your fuelling on long training rides so nothing is new on the day.
