No, but you will have to put in the grunt work later.
You are still in the process of building base miles, developing a high cadence style early on will pay benefits in the long run.Your 42/17 gives 65GI, a bit short of the ~70GI we used for winter fixed gear training but far preferable to slapping it in the big ring and grinding along as many new riders are wont to do.

Riding distance builds endurance, riding hills builds strength & doing sprints builds speed. Just coasting along after the summit is a waste of momentum, get on with it and build momentum for the next climb. Your big ring is for the downhills while getting base miles in to maintain a high efficient cadence and have enough gear under your legs that you are not dangling from the saddle at downhill speeds.

This is where the work comes in, ease into it but one must do the work to become proficient, or not. Intervals come next & time trials.
Your choice.

A well selected gear range is one that is as tight as possible for efficiency with a low enough to climb the biggest ascent in the area w/o undue stress and as big enough gear to fly down-wind-down-hill w/o spinning like a hamster in a cage or plodding.
