Beyond the plan

Everything that keeps a season going.

What a good coach does beyond the calendar: strengthen, protect, readjust, explain.

  • Strength work, built into the plan

    Strength sessions chosen for your sport, your time and your equipment. They follow the season, from foundations to pre-race upkeep, and target your weak spots first.

    FoundationsPowerPre-race

  • Coming back from injury

    A very gradual return programme: less impact, less climbing, gentle alternatives and strength work aimed at the injured area. To start once your doctor gives you the green light.

  • A plan that readjusts

    A missed key session is moved to a free day within the next three days. If there is none, no catching up: next week’s sessions are slightly shortened, so you ease back in. How you felt after each session shapes what comes next.

Reviews

What our users say.

4.8/5

  • “I used to spend more time looking for a plan than following one. Now I have my sessions, I know what to do and I stick to it. Really glad I tried it.”

    Thomas · Running

  • “Training for my first half marathon and honestly, I’m getting into it! I even look at my next sessions ahead of time, when before I was mostly looking for an excuse not to go out 😂”

    Camille · Running

  • “Simple to follow and really handy with the watch. I start my session and off I go.”

    Julien · Running

  • “I took Endu to prepare a trail race with friends. I really like having my week already organised: it motivates me and I enjoy my runs more.”

    Émilie · Trail

  • “What I like is no longer asking myself a thousand questions before going for a run. I follow the plan and I enjoy training.”

    Nicolas · Trail

  • “With work and the kids, I thought I’d struggle to follow a plan. In the end, having a structure helps me a lot. Running has found a real place in my week again, and it feels good!”

    Julie · Trail

  • “A good find to prepare my swimrun! It’s nice to find a plan for this sport. I’ve recommended it to my teammate.”

    Antoine · Swimrun

  • “I run more regularly and, above all, with more desire. For that alone, I’m delighted.”

    Laura · Swimrun

  • “For triathlon, having all three sports in the same schedule really makes my life easier. I spend less time organising my training and I still enjoy following it just as much.”

    Maxime · Triathlon

  • “At first I just wanted to try it. Now checking the next day’s session has become my little evening ritual 😊”

Questions

Your questions, answered.

How is my plan built?

Endu starts from your goal (race, distance, date), your experience, your MAS (maximal aerobic speed) and the days you can train. The build-up is split into phases (base, build, specific, taper), with load and recovery cycles. The engine applies training rules, with no artificial intelligence: the same profile always gives the same plan.

What if I miss a session?

Mark it as missed. If it was a key session, Endu moves it to a free day within the next three days. If there is none, no catching up: next week’s sessions are slightly shortened, so you ease back in. How hard each session felt also adjusts what comes next.

I'm a beginner, is Endu for me?

The plan adapts to your declared level (beginner to semi-pro): starting volume, progression and intensity change. Endu also offers a "Discovery" mode without a race to build a base first.

Which sports and races?

Road and track running, trail running, swimrun and triathlon. You can prepare several goals in the same season, say a trail race in June and a swimrun in September: Endu brings them together in one plan. With no race in sight, a maintenance or discovery programme is also possible.

How much does it cost, and how do I cancel?

14-day trial, cancel anytime, then €7.99 per month with no commitment, or €59.88 per year. You cancel online from your account, and it takes effect at the end of the current period.

Is there a mobile app?

Endu installs on your phone without going through the App Store or Google Play: open endu.fr in Safari (iPhone) or Chrome (Android), then add Endu to your home screen. On iPhone, tap Share (in the ⋯ menu on iOS 26), then “Add to Home Screen”. Endu then opens full screen from its icon, like an app.

What do you do with my data?

It is used to build your plan, manage your account and write to you about the service; the details are in our privacy policy. It is never sold, and you can delete your account and all your data from your profile, at any time.
