First half marathon training block

Going to start training for my first ever half marathon starting in January, and I’m curious how I should balance weight training with my running schedule. The Nike Run Club app that I’ll be using has me running 5 days a week (mostly easy/recovery runs with one day of speed work per week). Should I continue to weight train 3 days a week (push/pull/legs split) during the block? Or should I decrease that to 2 days a week?
