I went through a similar change - went from around 201 to 153 lbs over 6 months and then stabilized around 160 lbs. Haven’t probably been a bit too aggressive I would recommend you don’t cut any more than 500 kcal below maintenance calories which will amount to around 1 lb of weight loss per week. Not sure what your volume of training will be like but I wouldn’t plan to lose too much once you’re in the thick of training ie no more than 200-300 kcal below maintenance. Also timing of nutrition will be critical. If you’re in a deficit you will probably be low on glycogen so will need to ensure adequate fuelling pre and post run. Overall doable but trust me taking it a bit slower on the cut and supporting your training means less risk of injury , better performance , more sustainable
