Restrictive Covenants

I have a 12-month restrictive covenant in my contract (under UK law) that feels quite limiting. I’m seeking some knowledgeable advice on how to handle this situation. Should I challenge it, consider leaving the industry (which I’m hesitant to do given my over 10 years of experience), or explore opportunities abroad?

The clause states that I cannot solicit or attempt to solicit any Restricted Business from Candidates, Prospective Customers, or Customers. The term “Restricted Business” refers to recruitment within the Finance sector.

I would greatly appreciate any guidance!
