...the eight-day, 707km stage race through the Western Cape mountains is likely to punish them all...the mountain bikers will ride as far as 140km in a day and will climb a cumulative total of 14550m into the sky over eight days.
The Cape's sharp and loose sandstone rocks will maul tyres. If the southeaster is not blowing a gale, midday temperatures are likely to soar into the 40s. If not, the riders can count on rain and cold.
Anyone fancy signing up for the 2012 event: http://www.cape-epic.com/
