Getting data to your coach anyway
Ride files (FIT/GPX): upload them to Intervals.icu — they sync into LeCoach automatically with all data, and your coach can analyze them. How that works.
Test results, lab values, plans as text: paste the numbers as text in chat. The coach handles pasted tables fine ('my lab results: VO2max 58, LT1 210w, LT2 285w...').
Anything on a screenshot: type over the relevant numbers — usually just a handful of values matter.
What the coach can already see
Remember that everything in your Intervals.icu account is already in front of your coach — activities with full interval data, wellness, zones, history. Most 'can I show you this?' cases are already answered by what LeCoach can analyze.
