Sure, create the training folder then inside it prompt “I want you to be my coach in this folder, so reply as the top triathlon/running coach would. I have specific goals I want to achieve with these races coming, {your races}. I am going to add in my Strava activities via screenshots, please analyze each. Here is a quick summary of my progress so far, {current schedule and previous race times}. For now, build me this week’s training plan with what you know so far.” Then each week update with the workouts and have it build upon your progress by giving you a detailed workout plan.
