- do you have a specific warmup?
- do you clean the slide/chain?
- do you do some mobility/flexibility exercises beforehand?
- do have a cup of coffee?
- music?
- do you have to take certain medication?
- do you do nothing different and try to trick your mind into thinking you AREN'T about to hurt yourself?

...these sorts of things. The reason I ask partly is because I've got into the habit of using olbas oil on cottage wool and putting it up my nose (cyclists sometimes do this). Although it does clear your nose/head I really don't think it's anything other than psychosomatic but I have noticed it helps put me "in the zone".
