Tuesday’s swim is missed, and that’s fine. Don’t add it to today: keep the tempo run as planned.

Bike
On your own? Your training partner builds the weeks.
Tell it your days, your hours and your long day. It builds a plan to race day inside that time, and nothing reaches your calendar until you accept it. It’s an AI, and it says so.
I can train six days a week, up to 10 hours. Long ride on Saturdays.
Your training partner
Here’s a 16-week plan to Lakeshore. Every week stays inside your 10 hours, the long ride is on Saturday, and the last three weeks ease off so you start fresh. Have a look before anything goes on your calendar.

- BuildWeeks 5–10
- PeakWeeks 11–13
- TaperWeeks 14–16
Have a coach? Bring their plan.
Drop in the PDF, Word file or spreadsheet they sent, or paste their message. Splitpace puts every session on your calendar in their words and shows you each one before it lands. The AI training partner answers questions about it and never changes a thing.
Coming soon: share how it’s going with your coach, from what’s done to how each session felt.

Nothing slips quietly.
Every day shows what’s planned, a missed workout says Missed and waits for your call, and the week adds up. With Strava connected, finished sessions link themselves; report pain and training goes on hold until it’s checked. Share a finished workout with your crew.

Hi Maya, I saw Tuesday’s run stopped early and you said your calf felt tight. How is it today? Let’s talk before Thursday’s intervals.

Questions before you start.
Do I need a race to start?
No. The pacing planner works for any distance, and you can add workouts to your calendar without a race. Your training partner builds its training plan toward a race, so add the one you’re aiming for when you have it.
Is your training partner a person?
No. Your training partner is an AI, and it tells you so. It isn’t a qualified human coach or a clinician. Every change it suggests is checked against training limits before it can reach your calendar, it never piles missed training back on, and nothing changes until you accept it.
I already have a coach. Is Splitpace for me?
Yes. Add the plan they sent you, from a PDF, a Word file, a spreadsheet, a photo or a message. Splitpace puts it on your calendar in their words and links your Strava sessions to it, beside your pacing and fueling. The AI training partner answers questions about it and never changes it. Coming soon: share how it’s going with your coach.
I’m a coach. Can I use Splitpace with my athletes?
Yes. Today your athletes can add the plan you send them and train to it in your words, with Strava linking each session to it. Coach accounts are coming soon: invite your squad with one link and see every athlete’s week against your plan in one place. Tell us about your squad on the Contact page.
What does your training partner read about me?
Only what you agree to. Before you talk to it, a card lists what it will read: for example your plan and workouts, your check-ins and notes, and your Strava sessions with heart rate, pace and power. Your email address, photo, GPS routes and calories are never sent. The Privacy Policy has the full list.
Can I use Splitpace on my phone?
Yes. The website works in your phone’s browser today. The mobile app, with race mode and lock-screen widgets, is coming soon.
Do I need an account?
Not for the pacing planner: build a plan and copy it without one. An account keeps your races, plans and training in sync across your devices, and it’s what your training partner and Strava connect to.
Which races can I plan?
Sprint, Olympic, half and full distance triathlons, plus your own swim, bike and run distances.
Your race is on the calendar. Start today.
Splitpace is built for age-group triathletes who train around work, family and everything else.
