Most training apps hand you a plan and wish you luck. Soffri ("you suffer" in Italian) tells you whether you actually followed it. BUILD A PLAN AROUND YOUR RACE Your distance, your date, your week. 50K to 200 miles, with elevation and time-on-feet built in, because an ultra is not a long marathon. EVERY RUN, GRADED Your runs sync in and get scored against what the plan actually asked for: distance, elevation, and effort. No participation trophies here. Just an honest read on whether you are on track or kidding yourself. THE PLAN ADAPTS Miss a week and the plan reckons with it instead of pretending. Add a tune-up race and the weeks around it reshape. TRAIN WITH YOUR PEOPLE Build a crew, run challenges, and see each other's work. No race booked? Crews and challenges need no plan at all. YOUR RUNS, HOWEVER THEY ARRIVE Connect a watch and runs land automatically, or upload a FIT or GPX file. Works with Apple Health: Apple Watch and Garmin runs sync automatically. ON YOUR HOME SCREEN Widgets for today's run, this week and this month. The plan is in front of you before you open the app, and so is the grade when you get back. Go get your suffer on.
