They completed the race - the longest of its kind in the world - in 9:59:01 to finish 11th overall and more than 30 minutes ahead of their closest challengers, Port Elizabeth's Andrea von Holdt and Gail Willimott. Merrell Outventure's Catherine Townsend and Heidi Koen completed the podium.
In the men's section, brothers Heinrich and Pieter Lategan (Supercars) shaved 40 minutes off last year's winning time to defend their title successfully in 8:15:17. Dave Morison, Stuart Marais and Charles Keey (Blend Property Group) were second in 8:31:31 with last year's runners-up, Tony Conlon and Vickus Boshoff (Marsilio Projects), third in 8:38:51.
Stopforth, the reigning MTN Series champion, saw her season go up in dust in February after a training accident left her with a fractured pelvis and broken collarbone. "This result now gives me confidence for the rest of the season," which continues with the fifth MTN Series race in Cullinan on the Highveld on 28 August.
The 38-year-old from George in the southern Cape, who recently took part in the eight-day Trans Alp mountain bike race, said she and Olivier had come to the Trans Baviaans harbouring hopes of victory. "We also had it in the back of our minds to break 10 hours."
Stopforth said she felt the Alpine race had left her in top form for the first time since her crash and with Olivier winning the Carousel Classic in Gauteng the previous weekend, albeit on the road, they were quietly confident of a good result.
"Our tactics were to stay with the top men for as long as possible to gain an early advantage on the other women's teams. We were able to stick with them for 30 kilometres and this gave us the breathing space we needed going towards the first checkpoint (at 56 kilometres)."
According to Stopforth, they experienced some "rough" patches between the second and fourth checkpoints, with a headwind on this stretch not making things any easier.
They "refuelled" and mounted their lights at checkpoint four, situated 142 kilometres into the race at Bergplaas, which marks the end of the toughest climbing stretch of the event.
"Mentally the worst is over at that point," explained Stopforth. "We also had a tailwind from there, which is always welcome at the end of such a long race."
Stopforth complimented Olivier for making the transition from the road to the mountain bike in such emphatic style. "It's not an easy thing to do in an event of this nature. She's obviously a very classy athlete."
The pair only needed their on-bike lights for the last hour-and-a-half of the race, which has a 24-hour cutoff.
"We were already on the Neverender climb when dusk fell. That is the importance of a quick start - it minimises time spent in the dark and, therefore, risk."
Stopforth, who completed the event for the sixth time, said they were fortunate enough to escape mechanical problems and punctures and that the decision to use "soft tails" from their bicycle sponsors, Specialized, had paid off.
