Your race. Your fitness. Your training plan. Training for Leadville, Unbound, or your first gravel or mountain bike race? Dirt Factor analyzes the demands of your goal race, compares them with your current fitness, and builds a personalized training plan to help you get ready. Stop guessing. Start training with a purpose. NEEDED VS. CURRENT Pick a race and a goal: a finish time, or a place in your age group from past results. Dirt Factor models every climb, descent and surface on the course and gives you one honest answer: the power your goal takes against the power you have now. WHERE IS THE GAP? See the watts each climb and section takes, compared with your own race file. Know whether it's the climbs, the descents or the last three hours. BUILT FOR DIRT - Surface by segment, from pavement and gravel road to rough singletrack - A 1-5 technical trail scale: rough trail sets its own speed, whatever your watts - Altitude: the same watts feel harder at race elevation than where you train - Your descending, cornering and pacing, learned from your race files A PLAN BUILT BACK FROM RACE DAY - Blocks that work one intensity at a time, with your biggest gap as the training focus - Fits your riding days, hours, and indoor or outdoor riding - Race rehearsals before the big day, then a real taper - Every session explained: when to use it, how it feels and why it's in your plan - Targets in power, heart rate and feel, with trainer files to export CONNECTIONS Bring in your FTP, power curve and recent riding from Intervals.icu, Strava or Wahoo, and send your sessions to Intervals.icu or your Wahoo ELEMNT. Featured races include Big Sugar, Mid South, Unbound, SBT GRVL, Leadville and more, or upload your own course GPX.
