Good choice of tyres. Grudas - take note
Mine are in the post! No tubes or Haribos though.
Working away, I brought the bike with me, the town I'm in does Crit style racing (turned out to be more like track, do 1/2 or a lap each then pull out and drop onto the back) on a Tuesday (last Tuesday of the season though) It's an almost perfect circle velodrome style outdoor laps on a slightly banked track on road bikes, barrier on the outside and overhead lights.
30 minutes plus 2 laps for A grade. I went out too hard and did too many pulls on the front trying to drop people, the strongest rider put the hurt on when I pulled off the front every other lap and really dragged the other riders forwards, missed getting on the wheel once and off the back I went after 20 minutes. I struggle doing short turns in a bunch so it was good to practice a weakness of mine.
My excuses are; I'm not used to racing in the dark under floodlights which disorientated me, I got dizzy after doing so many laps, I couldn't see my Garmin timer as it was dark, I worked too hard at work and didn't save anything for riding, there was a nice smell of cooking food at one end of the track and I couldn't focus....

do any of those count?
Will have to try and get a few training rides in the rest of the week or I'll go backwards quickly, Bathurst is great for morning bunches, nothing like that here and working long hours means riding in the dark I think
Edit: with regards to rollers, very difficult to stand and pedal. I can do it, but not at a good cadence, maybe 55-75. On the road I'd do 70-80 cadence stood, they are just very difficult to balance on if you pitch the bike sideways with your out the seat style, almost fall off on every other pedal stroke and spend more time trying to balance than riding.
Sitting down, no problem with the resistance, I've had maybe 800w max power on mine, and ride a constant threshold of 320-340w on them no problem.
