Well the post is past the 7 day mark so I'd upvote it but it wouldn't pay out anything for you so here's a little something for your comment.

I have used weight training before as part of my training regimen on top of running 3 days per week when I was training for the Las Vegas marathon in 2016 and I must say I was shocked at how much it helped me maintain my speed over long distances and helped me get faster as well.

There is definitely value added for runners in adding resistance / weight training to their exercise regimen for sure. Thanks for sharing your post with me!
