Which bike today?

16°C, mostly sunny with a light SW breeze.
Which bike today? What a good problem to have- fixed gear or cyclocross?

‘Rode up Bannister Hill after riding up to Dalton. The big climb felt harder than last time, but this is the first time I have climbed up both.
Good ride at a decent pace.
