How challenging will this commute be?

I am potentially starting a new job in September, the easiest and quickest commute into Bristol city centre will be by bike. I know how to ride a bike but I would say that is the extent of my capabilities. It’s a 5 mile cycle, with 262ft of elevation gain and google maps says it’ll take 30 mins. Will this be challenging? For context I’m late 20s female who runs regularly but slowly.
