Just come back from the race. Was much much easier than the road race i did on Sunday. Lots of riders who don't know how to corner or hold their line very well. No organised riders going off the front. Found it very easy to stay in the bunch and a lot of it was about positioning.
Found myself boxed in many times when a few going on the outside. Only realised on the 2nd to last corner it was the last lap so started to make my way to the front. Managed to get around 15th (i think). About 150 riders rode!
Prefer road racing with Hills if i'm honest. Weedles out the weaker riders as there is no where to hide. Maybe it would nbe different in 3rd cat with some better organisation to split the group
Good experience though and my 2nd race done
garmin data from the race (again forgot to start tracking until 2 or 3 laps in)
