How each one plans
TrainAsONE builds your training from your running history and assessment runs, then recalculates the plan every day. Skip a session or run something else, and tomorrow changes to match. It gives you plenty of control on the web, and runners who like numbers tend to love it.
Ranner starts with a conversation about your goal, your week and your history, then writes a week-by-week plan. Each morning it looks at how you slept and recovered and how your last run went, and adjusts the day. When you want to change something, you just say it ("there's a wedding on Saturday", "my Achilles is sore") and the plan follows.
