V.O2 vs. Pacing (2025)
V.O2 vs. Pacing: Tradition-backed physiology or total custom control?
V.O2 is built on Dr. Jack Daniels’ renowned training methodology and VDOT pace system. It’s a proven choice for runners and coaches who want scientifically grounded plans, clean watch execution, and a large coach/plan ecosystem. Pacing, by contrast, is for runners who want AI-generated starting points they can truly reshape — down to every interval — with rich on‑the‑run audio coaching and shareable programs.
This article uses current, source-backed details (see References).
Key takeaway on price:
- V.O2 Adaptive Trainer: $12.99/month or $99.99/year (14‑day trial).
- Pacing: £4.99/month, £32.99/year, or £79.99 lifetime.

Common limitations to note
