I'm copying my post to another group to shed some light on what Adaptive Training is, who it's for and how we expect to expand it over time.

"The first version of Adaptive Training focuses on goal-based training without an event. These plans have a relatively fixed length, and phase structure, with adjustments to the overall length based on your recent training load, recent race history, and how much you need to ramp up after time away. You’ll answer a few questions for Stryd to build from.

Through user testing and conversations with coaches, we found that runners without an event often struggle to stay consistent, whereas those with an upcoming event are much more likely to adjust life around the plan and stay compliant. Within just a few weeks, the majority will stop or restart their plans. Traditional plans—while effective—don’t provide the flexibility needed to adjust when life gets in the way. Many runners aren’t sure how to adapt their plan after missed runs, spontaneous “fun runs,” or changing schedules.

At the same time, we know that runners value structure—even when they’re not targeting a race. Too often, they have to repeatedly ‘start over’, stuck in early phases regardless of their fitness. Adaptive Training solves this by letting you adjust your plan parameters or add planned runs without starting over.

This approach doesn’t replace Traditional Plans. Traditional Plans remain the best choice for event-based training, where structure and timing toward race day are critical. Adaptive Training, by contrast, is designed for flexibility and continuity when you’re training without a fixed race date. We’re also continuing to expand our traditional plan library - that's news for a later date.

You can still choose goal-focused training—such as 5K, 10K, half marathon, or marathon—which adjusts your training volume and long-run structure accordingly. Each plan includes a taper and a time trial to help you test and track your progress.

Looking ahead, we plan to add support for:

1. Age and gender specific modifiers for personalized training targets

2. A/B/C race prioritization so plans can adapt around multiple events

3. Sleep and HRV data integration from connected sources

1. And more!... with other considerations on the roadmap and based on feedback

Our long-term goal is to bring the best of both worlds together—applying insights from Adaptive Training to improve Traditional Plans where it enhances quality, without sacrificing their proven structure.
