Help! Advice required

Hi everyone!

So I am entered into National Masters Track Champs next weekend that starts at 16:00 on Friday. It’s the first time I’ve ever done following one season of track league that has been reasonably successful (couple of podiums in the ‘A’ group). Now an opportunity has arisen to ride a band 3 National B Crit on the circuit 10mins from my house on Thursday… I love racing and am reasonably prolific in crits but am I just screwing my legs over for a terrible reason??

The schedule of events for the track is sprint only on Friday, scratch on Saturday and points on Sunday… can I have my cake and eat it??

Thanks

skip the crit, focus on Nats
