BETWEEN YOU AND THE START LINE
Chapter one was picking the race. The rest of the road is below, in order, with the live product doing the work on the way down.
⏵ 02 · Know the course
SEE WHAT YOU ARE UP AGAINST
The race gave you a course file when you signed up. Drop it in and the course stops being a rumor. You get the real profile: the climbs with their grades, and the miles where the cutoff gets tight. The chart below is not a screenshot. It is the live instrument reading the actual Western States file.

THE PLAN STARTS WHERE YOU ACTUALLY ARE
It reads every mile you have run, works out your real fitness, and sizes the build to the course you loaded. A runner holding forty miles a week gets a different plan than a runner holding ten. Same race, different road.
- Week one is sized to your current fitness, not to a template's guess.
- Long runs are placed against the course: the vert and the terrain, not just the miles.
- Every session is editable by hand. Move it or delete it, no re-solve required.

The plan rebuilds itself overnight
You will get sick. Work will eat a weekend. The watch will show three runs in a week the plan wrote five for. Every night the plan reads what actually happened and re-solves the rest of the build from there. You wake up to a plan that starts from today, not from the week you were supposed to have.

When to push, when to back off
Sustainable form. Good ground for quality work.
Fitness (CTL) rises slow. Fatigue (ATL) moves fast. Form (TSB) is the gap between them. Ten weeks out, that gap decides whether this week is for pushing or for backing off. The chart below reads your last ninety days and says it plainly.

Written down before race morning
The plan turns into paper: what you eat each hour and where your crew needs to stand. All of it set before the nerves show up.

⏵ Why the cutoff math exists
One second
My first 50K had a nine hour cutoff. I crossed the line with one second left. One second, after four months of running and thirty one miles of moving. That finish is why this app treats the cutoff like a number worth engineering. Every projection carries a cushion, and the pacing plan shows where the cushion gets spent.

⏵ A note from the guy who built it
Jared, founder
I have run enough ultramarathons to know my problem was never effort. It was that none of my numbers talked to each other. My fitness lived in one app and only graded last week. My race pacing came out of a calculator that had never met my training. My fueling was a spreadsheet. The week before a race I would stitch it all together by hand and hope the guesses agreed.
Summit Line is what I built instead: one place where the numbers talk. It reads what I actually run, every mile and every grade, works out my real fitness, and builds everything off that, the training plan, the race pacing, the fueling, the cutoff math. Then it does the same with your runs.
There is no growth team here and no fake countdown timers, just one guy with a laptop and a hydration vest. If something is wrong, email me, and the person who reads it is the person who can fix it.

⏵ For the humans behind the runners
Coach your athletes on the same instruments
Bring your runners on. Athletes ride your seat, so nobody pays twice.
- Invite athletes by email; they accept and choose what they share.
- Prescribe workouts on a drag-and-drop calendar, synced to the watch.
- Read every athlete: fitness, fatigue, form, adherence.
- Run race day with them: pacing, fueling, crew, drop bags.
⏵ What it costs
No ambush, no sales call
Log runs by hand, use it free, forever. The logbook stays free.
Or $12/mo. The year saves you $45.
No card for the trial.
⏵ Questions, answered straight
The fine print, out loud
01Do I need a card to start?
No. Sign up free, no credit card. You can log runs by hand and use the app for as long as you like before deciding on anything paid.
02What happens when I miss runs?
The plan reflows overnight. Miss a week, get sick, travel: the next build re-solves off where you actually are, not where the original template assumed you would be. You can also edit any session by hand.
03Does it work for road races too?
Yes. The coach that handles mountains handles your marathon: same fitness read, same course-aware pacing, same plan logic, just tuned to easier terrain. It shows its range on the long stuff, 50Ks to hundred milers, big vert, heat, night sections, cutoffs, but a 5K, half, or marathon runs on the same engine.
04Which watches sync?
Coros, Garmin, Suunto, and Apple Watch connect directly with read-only access; your runs sync in on their own. We never change your activities and never sell your data, and you can disconnect any time.
05What happens after the trial?
It is free to start, no credit card. You can log your runs by hand and use the app for free for as long as you like. The watch sync, the coach, and the AI are the paid features, $99 a year (which saves you $45 over paying monthly) or $12 a month, and you only decide if and when you want them.
06Can I edit the plan myself?
Yes. Every session is editable: drag it to another day, swap the workout, change the mileage, delete it outright. Nothing forces a full re-solve unless you ask for one.
