Road distances: enter a 5 mile, 10K, half marathon or marathon PR and get race-pace rows next to your training zones. Miles or kilometres, your choice. Forecast paces: pick the practice time and every pace is set for that hour's heat, so a 10 am board is right at 3 pm. Coach notes on the workout board, and share cards for the board, today's paces, the heat, a new PR and a finished session. Log a session: type your reps and see hit, hot or cold against today's band. A default athlete that loads on launch, "View paces" on every roster row, and a profile screen for signed-in coaches. Resources: how it works in the coach's own words, Laktic Pro preview, upcoming courses and plans. Smoother motion, clearer colours, larger touch targets, and a long list of small fixes.
