yes that is a pretty dang good time. to get faster now you need to focus mainly on weight training like squats, deadlifts, calf raises, ect because your muscles aren't developed do weights 3 times a week to the point where you have worked every running muscle (hip flexors, quads, hamstrings, butt ect.) to near its extent of performance. then do speed training like uphill sprints which increases speed-strength downhill which increases stride rate and stride length and prctice your sprint events for track. never put two strength or two speed days in a row. the other two days I didn't mention are for rest. hope this helped. if you need anything else just check my profile for my e-mail.
