TrainingPeaks is one of the world’s most recognized platforms for planning and analyzing training in endurance sports like cycling, swimming, and running. That said, in today’s endurance preparation, concurrent strength + endurance has become a fundamental pillar. For this combo to truly work—and to prevent strength work from negatively affecting endurance performance—it’s essential to control execution velocity in the gym.
Many coaches already use TrainingPeaks as their main tool to manage athlete training loads. That’s why at Spleeft we wanted to go a step further: not only offering a powerful solution to record and analyze strength-training data via VBT (Velocity-Based Training), but also integrating that data into the platform coaches already use every day. This way, they can get a clear at-a-glance summary of each strength session inside TrainingPeaks and, if they want deeper analysis, jump straight into Spleeft to explore all the details.
Until now, Spleeft sessions recorded with Apple Watch were synced through the HealthFit app. That’s no longer necessary: all users can now connect Spleeft directly with TrainingPeaks, even if they don’t use an Apple Watch.
In this article, we’ll show you how to link your TrainingPeaks account with Spleeft to sync your workouts and how to interpret VBT data inside TrainingPeaks, a platform that, up to now, hasn’t provided specific support for these metrics.
How to Sign In to TrainingPeaks From Spleeft
Ir a Settings → Training Peaks and sign in with your account.
To upload data to TrainingPeaks, make sure “Write files” is enabled. If you also want Strength Builder workouts to sync in, enable “Read Workouts.”
After signing in, choose whether you want new workouts to sync automatically.
- Apple Watch sessions will sync when you end the workout y open the app on your iPhone—as long as auto-sync is enabled.
- Likewise, when you import data via our iOS/iPadOS action extension from another VBT device, your session will sync automatically if you select your personal profile.
Note: If you’re a coach, you can’t sign in with your athletes’ TrainingPeaks accounts—only with your own personal account.
Manually Syncing Data to TrainingPeaks
If you only use Spleeft on your iPhone (e.g., measuring velocity on machines like the leg press), you’ll need to force sync when you finish the session:
History → tap the day you want to sync → tap the cloud-with-arrow icon at the top of the screen.
Reading Planned Strength Sessions
If you use TrainingPeaks’ new Strength Workout Builder, you can sync those sessions into your Spleeft app for easier access. This sync is not automatic yet. Go to:
Train → Workout Sessions → select date range → Sync.
TrainingPeaks currently doesn’t export many strength-session details or natively support VBT. It only exports the title, description, and exercise names.
How to Interpret VBT Data in TrainingPeaks
If you’ve followed the steps above and synced your first data, you’ll see the session on the TrainingPeaks web platform. Spleeft syncs heart rate only for sessions recorded with Apple Watch. Since TrainingPeaks doesn’t truly support VBT yet, you’ll find your metrics in these channels:
Strength (VBT) parameters
Execution velocity: en el Speed / KPH channel (units are EM).
Load: mapped to the Cadence / RPM channel.
Power: en el Fuerza channel.
Jump-training parameters
Jump height: en el Torque / Nm channel.
Load: shown again under Carga.
Notes on time series: The time series won’t necessarily match the exact timestamp of each rep. Only the first rep is placed at its exact time, and the rep order is preserved.
We recommend turning off data smoothing so you can view the signals clearly.
You can also see the exercise order in the workout comment.
This way, you (or your coach) can quickly visualize your strength-training data. If something stands out, they can open Spleeft on iPhone, iPad, or Mac for a more detailed view—thanks to our new athlete–coach iCloud sync.
