Alex Harris reached Stuttgart support station at approximately 16h35 according to Tracker. That means that, after narrowing the gap between race leader Martin Dreyer from Hofmeyr to Elandsberg, to around 5.5 hours, the latest stage from Elandsberg to Stuttgart saw the gap remain more-or-less stable at near to 5 hours 30 minutes. Dreyer pulled into Stuttgart at about 11h00 this morning and left at around 11h25.
At 16h34, Martin's Tracker reading put him not more than a few kms from Grootdam support station. He is probably at the station by now.
The Freedom Challenge
The Freedom Challenge Race Across South Africa is an "unsupported" non-stage mountain bike race of approximately 2,300 km across South Africa. While recent winners have won in around 11 days, the race cut-off is 26 days. The race starts in Pietermaritzburg in early-to-mid-June, and ends in Paarl near Cape Town. Temperatures are known to drop as low as minus-10 deg. Celsius. While there are periodic "support stations" which will feed and accommodate riders should they require, the race is unsupported in the sense that riders must carry their own clothing and equipment, are responsible for their own maintenance and navigation (without the aid of GPS), and there are no marshalls or safety officials on the course (Race monitoring is done by satellite tracking). Estimates of cumulative ascent are around 37,000 metres, and the highest point on the route is approximately 2,700 metres above sea level.
