Just got back from a biking/camping trip. I do think the biking has helped my running. I have never been a fan of biking, but I started doing it after I injured my foot in order to keep my aerobic fitness up.
I was hoping to do a jogging-hike while we were on our trip, but we got rained out and left before we could go on the run. I still haven’t had the opportunity to do one of those around home, since it actually requires planning: I have to drive to get to a trail. 
The half marathon I signed up for is on November 21. Yesterday I “ran” 10 miles. My feet were pretty tired and my ankle a little irritated for the rest of the day, but today they are feeling fine. I may actually make that half marathon after all!
@Amanda1, I’m impressed that doing 200 km in a month is getting your mojo back. That is some mojo!
I never forget about running now. I don’t run when it’s steep uphill and almost always run when it’s some nice downhill (there is one where I don’t run, too steep). I expect to get better.

I did my steepest hill route yesterday, the steepest of the local hills. I rode my bike to the start, met a friend who I haven’t walked with before (we are both cheerleaders on a MOST diverse cheerleading team) and showed him my secret track that begins easy, then gets steeper and steeper, and even steeper. Never see anyone else on it. After a few minutes rest at the top I showed him the best set of big stone stairs which lured us into a bit of stair sprinting. There’s nothing better than fast stair running!
