Hills suck so bad. But you can always jump off, walk alongside your bike for a bit, and jump back on. I find that gives me a much needed boost, of course doesn’t work as well if it’s a really steep hill but it does on moderate grades. The trail in ride most often is uphill for several miles, it’s not steep but it’s definitely long and steady. When I first started I would start at the bottom of the hill and would stop and rest all the tome. I’d ride a short way up the hill, getting passed by runners, and then ride back down wishing I could keep up with my husband who would ride all the way up the trail and back. I just kept at it and I slowly got faster and stronger and now I can do that hill without evening thinking about it. It gets easier so fast if you just stick with it.
