The first coaching assistant for endurance athletes. Part world‑class coach, part trusted assistant.
Part world‑class coach
Pace works from your real training data: every activity, every plan, every night of sleep. Talk to it like you'd talk to your coach.
How did Sunday's race go, honestly?
Strong. You held 4:12/km through 30K, then faded about 9 seconds a kilometer once the hills started. Fitness wasn't the limit, fueling was: your last gel was at 24K.
Part trusted assistant
Registrations, bib pickups, gear and travel. The logistics that eat into your week, handled in one message.
Register me for Boston the moment it opens.
Done. Your qualifier clears the cutoff by 4:31. I'll submit the moment your window opens and send you the confirmation.
Pace checks in first
Great coaches notice things. Pace keeps an eye on your calendar, your training and your recovery, and checks in when it matters.
Just checking you booked your bib pickup. It's this Friday.
Big effort today. Don't forget to hydrate and keep tomorrow easy.
Rain until 9 this morning. Want to swap today's intervals with Saturday's easy session?
iMessage, Telegram, the Paceline app or the web. Type it, or send a voice note after a session.
Garmin, Apple Health and COROS. Workouts land on your watch.
Real numbers, plain language, and the why behind every change to your plan.
About us
We train, we race, and we built the coach we wanted. Paceline Labs has offices in New York and Toronto.
Chief Executive Officer
The visionary. A designer and VC whose own experiment coaching himself with AI became Paceline, with the hustle to match. Races triathlon for Uzbekistan; if there's a podium within driving distance, he's probably on it.
Chief Operating Officer
The serial founder. Built an early mobile messaging startup and then Perpetua, both exited, with five years as an engineer and PM at Google along the way. Runs product, and runs everything else too: four marathon Majors, two HYROX World Championships, and one Ironman he'd rather not talk about.
Chief Technology Officer
The genius. PhD in computational linguistics, then years as a principal research scientist building personal assistants at Nuance and Cerence. Fastest Canadian at the 2024 London Marathon, though he'd never bring it up.
