It jumped from 15km to 20kms. It was an out and back course with a small hill at the 9km which continued to the turn around point.
Had a good run out, probably averaging 32-33km/h. I only had 3 riders pass me. (I'm only D grade) Having a rider pass was an advantage, although sitting the required 25m behind, I could still use them to pace myself.
Coming back was a different story.

I dropped as low as 25km/h at around the 14km mark but managed to pick it back up to 28+ over the last few kilometres.
I felt good after the race until I cooled down and found the tops of my hamstrings were quite sore. I don't know if it was the effort I put in or the fact my legs were tiring so I tried a few different muscles to push and pull the pedals.
The time on my computer was 2 minutes slower than the official time so I'm sticking to the official time of 38m 51s giving me an average of about 31.1km/h. I was aiming for 30km/h so I'm happy with the result. I believe I was 3rd or 4th in my grade. Hard to say as they read the names and time out in the start order not the results order.
We had Ruth Corsett in the race. She's the current Australian road champion and I didn't object to her passing me but I was a little dishearted when a 60+ year old sailed past like I standing still and to make it worse he rode 30kms to the race start and I drove there.
My daughter did a lot better. Lucky juniors only had to do 4km out and back.
It was her first race and overall (boys and girls) she came second, beaten only by a filthy boy and she easily beat the other girls.
She would have almost beaten the first placed boy but she wasn't sure which marker to turn around so she went for the furtherest one and then hit it so lost a bit of time by riding further than the rest.
She averaged 30.65km/h which isn't too bad for 13 years old.
