13 y/o cyclist – are these times any good for my age?

Hey, i've been cycling for most of my life and around 6 months ago on and off i started on a road bike specifically the pinnacle laterite 3. I've recently racked up a few PR times and I was wondering if these were considered good? Whole of richmond park: 26mins and 4 seconds avg pace 26km/h 10k: 17:35 avg speed 34.1km/h 5k 9:58 30.1km/h 5 mile 16:54 28.6 km/h

Thanks in advance (i'm getting clip in pedals soon)
