Restrictive Covenants Advice Needed

I’m currently facing a 12-month restrictive covenant in my contract (under UK law) that feels quite limiting. I’m seeking some informed opinions on how to approach this situation. Should I challenge it, consider leaving the sector (which I’d rather not do after 10+ years of experience), or explore opportunities in other countries?

The covenant specifies that I cannot solicit or attempt to solicit any restricted business from candidates, prospective customers, or customers, with “restricted business” being defined as recruitment in the finance sector.

Any guidance or advice would be greatly appreciated! Thank you!
