After a week or so layoff due to a cold, went out on an early morning ride to do a circuit of Lake Illawarra, sticking as close as is possible to the lake's edge (except at Primbee, where I stayed on the main road that bypasses the village). I used the main road as far as Warrawong, since it was quiet at that time, then followed bike paths and backroads, apart from a section of the Princes Highway through Kembla Grange as far as Kanahooka Rd. This was the first time I'd done this. After reaching the lake at Windang I largely followed the route of an annual 40km annual charity ride held in May that starts at Warrawong. The terrain is mostly flat except for some sharp hills the section through Koonawarra & Dapto Heights, where I took a more challenging route than the charity ride.
