Allyson is an AI running coach on iPhone, made for women who run. Tell her your race and the days you can train, and she writes your plan, from a first 5K to a marathon. When your week changes, message her and she moves the plan around it. If you run with a Garmin, Coros, Polar or Suunto, your paces come from your own runs. Your plan is free, and your coach is free for your first two weeks.
