I'd count on 3.5 hours to hike from the train station in Grindelwald to First, excluding breaks, so 4 hours is more like a realistic minimum. If you like hiking, are in good physical shape and are willing to make a day out of it then it will work. Mind that it's more than a 1000 m ascend. It would be too much for me, certainly in summer.
