Longrun: Marathon Training

You have never run a marathon. You have a date, a start line, and a number that looks impossible from where you are standing today.

Longrun turns that into tomorrow morning.

Longrun is a marathon training plan for people running their first one. Tell it three things: what a good race looks like to you, how far you run right now, and which race you are training for. It counts back from the real date and builds the twelve to twenty weeks in front of it. Three runs a week to start, every one of them easy. One long run every Sunday, growing about a mile at a time. A taper that arrives before you think you need it.

Then it hands you one day at a time.


A TRAINING PLAN THAT MOVES WHEN YOU DO

Every running plan meets real life somewhere around week three. Yours will too.

Tell Longrun you missed a run and the week reshuffles itself. Miss a hard session and the next one becomes an easy run while the long run holds its distance. Miss a long run and next Sunday holds at this Sunday's number, and the growth waits a week. Miss two in a week and the following week eases about 10 percent, then rebuilds.

Every change is shown to you, in a sentence, with the reason. That is what an adaptive training plan should mean.


EVERY DAY, ON ONE SCREEN

Today opens on the session you have, the pace range to hold it at, and roughly how long it will take. Underneath: your water, your food, last night's sleep and HRV, and this week's seven bars filling in.

RUN TRACKER — GPS distance, live pace, mile splits, and coaching cues that arrive when you need them. Runs from your watch arrive through Health Connect too.

FUEL — A daily calorie and carb target that changes with the kind of day it is, a meal plan you log with one tap, and long-run fueling that counts your gels.

BODY — Sleep, HRV and resting heart rate from Health Connect. An acute-to-chronic training load ratio with the 0.8 to 1.3 sweet spot marked, so you can see an injury coming. Shoe mileage, so you retire a pair before it retires you.

PROGRESS — Total distance since week one, planned against done, longest run, easy pace, and a finish-time estimate from the runs you have actually done.


RACE DAY, ALREADY REHEARSED

Choose from 377 races, all seven World Marathon Majors among them, or type in your own marathon or half marathon and its date.

From that moment the Race tab counts down. Your finish time, your marathon pace per mile, how many gels to carry and when. A race-week checklist that opens seven days out: cut the volume, carb-load, pin the bib, arrive 75 minutes early. Course profile, typical weather, your bib number and your wave.

By race morning you will have practiced all of it.


WHO IT IS FOR

Beginner runners with a marathon on the calendar and no idea what week one looks like. Runners stepping up from 5k or 10k to a half marathon. Anyone who has downloaded a marathon training plan as a PDF and abandoned it in week one.


THIRTY-FOUR LANGUAGES, MILES OR KILOMETERS

Fully translated into 34 languages, right-to-left scripts included. Switch between miles and kilometers whenever you like.


WHAT LONGRUN LEAVES OUT

No chatbot. No AI writing your training. No feed, no kudos, no follower count. An adaptive running plan, the day in front of you, and a coach's voice saying what a good coach says: go slower, eat something, sleep.
