I'm currently training for a 3 day trail running stage race where the 1st day is 20 miles with 2k-3k elevation gain, 2nd day is 18 miles on flat trails, and 3rd day is 22 miles with 3k+ elevation gain. Over the last few months I've only managed to run 3x a week and have dropped strength training from my schedule due to lack of time. The race is 8 weeks away and my work schedule has settled down allowing me to train more. For the 8 weeks leading up to the race I'm wanting to run 5x a week, In 3 day and 2 day blocks and my weekly mileage peaking around 70 by week 6. here's what my schedule looks like
Sun- 60-90 minutes flat/undulating
Mon- 3-5 hrs hilly
Tues- Rest
Wed- 60-90 minutes hilly
Thurs- 2hrs flat/undulating
Fri- Rest
Sat- 3-4 hrs hilly
My problem is I really feel I need to strength train (lower body & core) but don't know where to put it in the schedule without risking overtraining or just having dead legs on my runs. Any advise, ideas, would be great!
