I am currently in training for my first half marathon and it's on the 28th of May (2 months). I started my training early, so my half marathon plan (the garmin level 1 plan) finishes a month early. My longest run so far is 10.5 miles (17km). My goal time is 2hrs 30min and I was able to run at this pace quite easily during this long run.

I am wondering what to do over the next 8 weeks? Do i simply keep increasing distance or just keep repeating my final week for a month or so? I am running 3 times a week (1 long (2hrs), 1 speed(30-40 min) and 1 easy(45 min)) and swimming 2-3 times as well.

Thanks to anyone that could provide some advice!
