I've just bought a Forerunner 265 and added a plan to run a 10K in 8 weeks and 4 days.
I couldn't create a plan other than the Garmin because the race is too soon.
So, I ran my Benchmark run today, but nothing was added to the calendar afterwards. I thought the plan would adjust based on my benchmark, but it seems no training sessions will appear, and I need to quit and create another plan where I'd lie about the race date
