Runner with questions

Hey all, I’m new to the community, just purchased the 8 wk weight loss plan, and aim to start Monday. Here’s my question: I am a distance runner who typically runs 3x a week (2 - 4 milers and a 5-6 miler) with occasional strength and yoga workouts in between. In spring and fall, I train for and run half-marathons. This is my “off season” and I’m wanting to increase my strength and flexibility. Is there a good way to adapt the plan without completely giving up running? I don’t want to hit my next training season with no distance endurance.

Background in case it is relevant: I am a 50 year old menopausal woman who has always been healthy and active. In the last 5 years, I’ve seen a weight creep of about 20 lbs. In the last year, I’ve noticed a significant loss of muscle and flexibility. Basically, menopause is not being kind, and it is time to preserve what I have!

Are there good adaptions or do I need to sacrifice the exercise I enjoy for the exercise I need?
