Transition

transition.fun·Health & fitness·🇺🇸

The service offers training plans that adjust dynamically to an athlete's starting fitness, ongoing progress, and changes in schedule or external conditions such as weather. This adaptability aims to remove guesswork from triathlon preparation by using Transition AI to personalize the training experience.

The platform provides a full three-sport plan tailored to individual needs, with immediate feedback on workouts and the ability to quickly modify plans in response to interruptions or changes in athlete performance. In addition to endurance training, Transition includes features for strength and flexibility guidance, as well as nutrition advice. Built-in nutrition logging, with a focus on protein tracking, is highlighted as part of the tool's offering. The app is described as clean and intuitive, catering to both beginners and experienced multisport athletes.

The service is available through a subscription model, with a risk-free 30-day trial period mentioned. The pricing is presented as more affordable compared to hiring a human coach. The tool is positioned for triathletes at all levels, including those new to the sport and those seeking to improve their performance in long-distance events. It also offers general maintenance and health-focused training plans for longevity beyond race-specific preparation.
