MandaRUN 2026 Half Marathon Training Plan (and Updates)

I signed up to run another half marathon! It’s the MandaRUN on November 22. It’s my second time going after a HM (the first). I’ve got about 10 weeks to train before race day. I used AI to help me come up with a training plan.

Revised plan (updated Nov 1)

After way too many 😷 days, I revised my training plan with AI. My goal has dropped from “PR” to “Survive.” My longest run to this point was 7 miles. Part 1 of the plan is to rest a few days to get over this sinus infection. Part 2 is tof build to an 8-mile long run (any day next weekend), then a 10-mile long run by Nov 14-ish, then 🤞.
