The number of sports retailers in the UK is set to decline as too many stores chase too few customers, according to a new survey to be released later this week. A report from consultancy Retail Intelligence entitled the 'UK Sports Goods Market' said that even the five leading UK retailers, which accounted for 30 per cent of the market in 1999 and include JJB Sports, Blacks Leisure, and JD Sports PLC, would come under increased pressure. This is because consumers prefer to spend money on technology and joining a gym rather than on new sporting equipment.
