Evidence
Numbers matter, but so does the rider behind them. These are the stories, source videos, training patterns, and outcomes that show how SEMIPRO thinks about progress.
SEMIPRO helps serious cyclists improve performance through structured training, clear coaching decisions and training that adapts around real life.
The examples below include race wins, event personal bests, improved power, stronger late-ride performance and successful training on limited weekly hours. Each example includes the rider context and source material where available. These are individual outcomes, not guaranteed results.
Every athlete record in the library, with the rider context and the evidence type attached to the outcome. Where a timeframe has not been verified it is left unstated rather than estimated.

SEMIPRO methodology

PRs shifted to the back half of rides

Greg is useful evidence for the training library because it shows a self-directed rider using structured capacity work successfully.
View the evidence for Greg: capacity work that held upEach page keeps the useful detail close to the story: who the rider was, what changed, where the source came from, and where a single example has limits. Some are athlete case studies. Some are methodology or coaching-background references. None are meant to pretend every rider will get the same result.
SEMIPRO uses three forms of evidence.
No single case study proves that a method will work for every cyclist. The value of this library is the repeated pattern across riders, goals and constraints.
