Targeting seperate parts of a URL in Optimizely with REGEX

I'm trying to target a set of URLs sharing the same template in Optimizely the https://chillisauce.com/hen/in-dublin/day

Specifically trying to target the hen/in- part and the /day part.

I've been testing this: /(hen)/in-.*/day[^/]+$

Although when testing the URL pattern in Optimizely it does not match.

Any ideas?

Thanks in advance

Charlie
