What it does
Everything a serious runner needs.
Nothing they don't.
AI coaching that knows your body
Your coach card reads every session you log — pace, effort, soreness, sleep — and gives you feedback that feels like it came from someone who actually tracked your training. Because it did.
Plans built around your life
Four paths: pick from 17 expert plans, generate a bespoke AI plan around your goal and schedule, build your own, or let the app shape training around your lifestyle. Gym sessions built in. Runs that make sense.
Analytics that mean something
ACWR training load, pace zones from your actual runs, race day predictions using Riegel projection, weekly coaching debrief. The same tools used by elite coaches — readable by normal humans.
Real coaches, in the same app
Connect with a verified coach. They see your logs, your wellness, your load — and coach you inside NextSplit. No switching apps, no screenshots, no WhatsApp chaos.
Training that keeps you honest
Your RPG character levels up as you train. XP, badges, streak fire, season leagues. Gamification that actually reflects your fitness — not just your app opens.
A community that gets it
Clubs, weekly leaderboards, virtual races with real finish times. Train alone, compete together. Season XP resets every month so everyone has a shot at the top.

Early feedback
From runners who've tried it.
“I've used Garmin Coach, Runna, TrainingPeaks. NextSplit is the first one that actually explains why I'm doing each session.”
Marathon runner, 3:41 PB
“My coach can see everything in one place. I stopped sending screenshots of my Garmin watch.”
Coached athlete, sub-20 5K
“The ACWR chart flagged that I was overreaching two weeks before my shin splints started. I wish I'd listened.”
