Running plans have come a long way. Back in the day, if you weren't working with a coach, you'd just get a training plan from a back issue of Runner's World or your local library's copy of The Complete Book of Running by Jim Fixx, and have at it with nothing more than a stopwatch and a tracksuit for 16 weeks.
Now, we have plans freely accessible online, the best running watches to provide professional-level guidance and pace information, and adaptive AI-tailored plans from the best fitness apps like Runna. Things have certainly changed, and it's no longer just about crossing the finish line. Now it's about posting your time on Strava with a pic of your medal.
