add planned runs (events/races)

As a cyclist who runs 2 to 3 times a week I miss the ability to add a planned run to your schedule like you can with a planned ride. I like to do 10k’s and half marathons from time to time, and always struggle to find a good way to add these kind of all out very impactful races to the planned schedule. I end up taking it easy as I see fit leading up to these races, but I would like to see JOIN do this for me.
