Both platforms generate structured running plans and push workouts to your watch. The difference is in the approach: Runna is a polished coaching app built around guided weekly sessions and a subscription model, while Get-Split is a data-first training engine calibrated to your VDOT, built for athletes who want pace-precise structured training with full Garmin integration and no monthly fee to access the core features.

If you already understand pace-based training and own a Garmin, Get-Split's edge is clear. The platform was built around the Garmin ecosystem from the ground up. Workouts are pushed as fully structured sessions — warmup, main set with per-interval pace targets, cooldown — not just a "run X minutes at effort 7/10." Your Garmin watch knows the exact pace zone for each step.
The calibration model is also more precise. VDOT (Jack Daniels' performance-equivalent VO2 metric) converts any recent race time into five training paces: easy, marathon, threshold, interval, and repetition. Every session in the plan references those paces explicitly. If you run a 10K in 44:30, your threshold pace sessions show 4:42–4:48/km, not a vague effort level. When your fitness improves — evidenced by a faster benchmark race mid-cycle — one click recalibrates all remaining workouts to match.
Get-Split also pulls activity data back from Garmin, not just pushes to it. This means the platform can track whether you actually completed a workout as prescribed, detect HRV trends that suggest under-recovery, and surface patterns across weeks of training. Runna relies on self-reported effort rather than data from your watch.
Cost is a significant factor for many runners. The full plan generation engine, VDOT calculator, Garmin push, and activity tracking in Get-Split are free with no time limit. Runna charges a monthly subscription to access its full plan features.
Runna's native iOS and Android apps offer a significantly smoother mobile experience. If you want to review your upcoming week, log how a session felt, and get a push notification when it's time to run — all from your phone — Runna's app is built for exactly that. Get-Split is a web app; it works on mobile browsers but does not have a dedicated native app for iOS or Android.
Runna's onboarding is genuinely beginner-friendly. A new runner who has never heard of VDOT or threshold pace can answer a few questions about current fitness and goals and receive a sensible plan within minutes. Get-Split asks for a recent race time or VDOT benchmark upfront — an appropriate question for intermediate runners, but potentially confusing for someone who has never raced.
The weekly coaching check-in in Runna — "how did this week feel?" — provides a low-friction way for athletes to signal that life got in the way or that they smashed every session and want more. This guided, conversational adjustment mechanism suits athletes who prefer to be coached rather than to manage numbers. Get-Split's recalibration is more powerful but requires the athlete to initiate it by running a benchmark.
Runna's in-app community features and coaching team provide a sense of accountability that a self-service tool like Get-Split does not match. For runners who need external motivation and community to stay consistent, that difference is real.
Get-Split's planner engine implements a periodised structure derived from Daniels, Pfitzinger, and Hanson methodologies. A typical intermediate half-marathon plan includes: one long aerobic run on Sundays, one threshold session (cruise intervals or a continuous tempo), one VO2max session (track-style repetitions), and two easy recovery runs per week. Volume ramps at roughly 10% per week with a mandatory down-week every fourth week. A tune-up race mid-cycle gives the engine a new benchmark to re-calibrate from.
Runna builds plans around a similar weekly structure — easy days, quality days, long run — but framed in effort levels and RPE rather than specific paces. For athletes who run without a GPS watch or who find pace targets stressful, this is more accessible. For athletes trying to hit a specific goal time at a specific race, pace precision matters, and Get-Split's explicit 4:10–4:20/km targets are more actionable than "effort 8/10."
Both platforms handle the taper well. Get-Split's taper is built into the plan template and reduces volume by roughly 20–30% in the final two weeks while preserving some intensity. Runna's taper similarly reduces load while maintaining session frequency to avoid detraining.
Get-Split is Garmin-native. The integration goes beyond workout push: it reads your completed activity data (pace, HR, laps, GPS route), syncs body composition from Garmin Health, and tracks HRV readings to inform a daily recovery score. If you own a Garmin Forerunner, Fenix, or Epix, Get-Split treats your watch as the primary data source.
Runna supports Garmin push through the standard Garmin Health SDK. It sends planned workouts to your watch, but the data relationship is one-directional. Your completed activities stay in Garmin Connect and are not read back into Runna for analysis. The same is true of Runna's Apple Watch and Polar integrations.
Both platforms connect to Strava. Get-Split syncs both ways and applies cross-source deduplication so you don't end up with the same run logged twice from Garmin and Strava.
Yes. Plan generation, VDOT calculation, Garmin sync, and activity tracking are all free. A premium tier adds unlimited plan history, advanced analytics, and multi-device sync, but the core training platform has no paywall.
Yes. Get-Split pushes structured workouts (warmup, main sets with pace targets, cooldown) directly to Garmin Connect. They show up on your watch as guided workouts, the same way Runna's Garmin sync works.
Runna's onboarding and mobile-first UX is smoother for beginners who want a guided experience. Get-Split requires more input upfront (VDOT or recent race time) which suits runners who already understand pace-based training.
Get-Split is a web app that works on any browser, including Android. Runna has dedicated iOS and Android apps; Get-Split's mobile experience is a mobile-optimised web interface.
Yes. Enter your current VDOT (or a recent race time) and your goal race date. Get-Split generates a plan from that point forward. You don't need to start from week one.
Get-Split was designed around Garmin first. It reads your activity history, syncs back structured workouts, and lets you manage the entire Garmin calendar from the web. Runna supports Garmin push but doesn't read back your Garmin activity data to calibrate the plan.
