This is part of the BikeSA Grand Slam Challenge series. See the whole event series here.

Grand Slam #4 at Strathalbyn is where the series separates the serious from the occasional. Departing from the Strathalbyn Show Hall through the Fleurieu Peninsula, this penultimate round stretches to 75km and 150km. These are the longest distances in the series before the grand finale. By this point, committed riders will have accumulated over 250km across three previous events. Strathalbyn rewards that investment.

The Fleurieu Peninsula terrain delivers rolling farmland, long sightlines and the pastoral charm of one of South Australia's most beloved cycling regions. At 150km, the Grand Slam option is a serious endurance test and the most important preparation ride for the October finale.
