INTREPID horse-riders throughout Worcestershire have the chance to take part in a trekking challenge in Canada.

The Guide Dogs for the Blind Association wants volunteers for the 11-day 90km Chilcotin Mountain Horse Trek Challenge.

The riders will rely on mounts and packhorses to carry essential supplies.

"This is a once in a lifetime opportunity," said Colin Hill, the association's overseas events manager.
