Seidur is an extension of Ellida that allows athletes to request personalized, adaptive training plans in the specific style of their favorite coach. For example, a run training plan that mimics the philosophy of svexa partner and multiple marathon record holder coach Khalid Khannouchi.
individualized, optimized, adaptive star coach training plans
Your Personal Celebrity Coach. Delivered by AI.
The gap between elite and recreational athletes has never been purely physiological — it has also been one of access. Elite athletes benefit from expert coaching, individualized periodisation, and continuous monitoring that recreational athletes and developing youth performers simply cannot access at the same level. Seidur, svexa’s AI coaching and personalized training plan solution, changes that equation by making the training philosophies of real, recognized, world class expert coaches accessible to any athlete with a smartphone and a wearable device.
What Makes a Great Coach?
Great coaches combine deep sports science knowledge, pattern recognition across hundreds of athletes, and the ability to individualize that knowledge to the specific physiology, goals, and life context of each athlete they work with. They adjust plans dynamically as circumstances change, communicate the rationale behind programming decisions, and maintain long-term development perspective even under short-term competitive pressure.
Each of our Seidurs goes through an extensive collaboration with svexa’s team to ensure we’re delivering closely on their philosophy. Seidur encodes these capabilities from each one of our real star coaches in an AI system trained on svexa’s proprietary dataset of elite and sub-elite athlete training records, performance outcomes, and physiological response data — one of the most comprehensive such datasets in the world.
How Seidur Works
An athlete connects their existing wearable devices — Garmin, Polar, WHOOP, Oura, Apple Watch, and others — to the svexa platform. Ellida analyses their training history, current fitness level (estimated from heart rate data using validated algorithms), stated goals, available training time, and lifestyle constraints. Then Seidur generates a personalized, periodised training plan specifically in the style of the real world star coach the athlete has selected.
The plan is not static. As the athlete completes sessions, Seidur evaluates their response — comparing expected and actual training stress, adaptation rate, and recovery metrics — and adjusts future sessions accordingly. If an athlete reports poor sleep, high life stress, or an upcoming travel commitment, Seidur modifies the plan in real time just as the real star coach would.
Science-Grounded Programs, Tailored by Real Coaches
Typical Ellida plans draw on established frameworks including traditional linear periodisation, block periodisation, and polarized training approaches — selecting and blending methodologies based on the athlete’s event, current training phase, and response profile. The scientific literature supporting these approaches is extensive, with foundational work published in sources such as the International Journal of Sports Physiology and Performance and the European Journal of Sport Science. Seidur goes further, applying the specific philosophy of each real celebrity coach to the different stages and blocks of training.
