FAQs
Why doesn’t this directory have tons of filters?
Because the fastest way to pick a race is usually a short, curated list — not a maze of filters. Open an event guide to see the details that change training and race-week decisions.
Where do the facts come from?
We store sources for each event and show a last-verified timestamp. If we can’t verify a time-sensitive fact, we mark it as unknown.
How should I pick a race date?
Choose a date you can realistically build toward, then train backward with a plan length that matches your base and recovery.
