Not allowed to work for a competitor

[frazerd]

I work for a small insurance broker and have been given an amended contract to sign which states that if I ever leave the company I cannot work for a competitor within a 30 miles radius of our office, for 12 months.
Is this restriction considered 'reasonable' in employment law? How could I go about accepting the contract but not this clause?
The company went on a 4 day week not long ago (since ended) and naturally some people are nervous to hang aroung if things get worse again.
Genuine legal response wold be appreciated.

Next time, maybe write oneself a note to remind one where one left it.
