The event will start at 1.30 pm at the Tri Site in Titikaveka.
Some cyclists will be aiming to complete the distance in under three hours, while others will be trying to hang in there with the main pack of riders for as long as possible and then complete the distance in their own time.
Not only will the distance and speed be a challenge, but also the wind and road conditions. All cyclists will have to prepare and carry their own liquids and nutrition to get them through the long ride.
As a practice, last Saturday a group of enthusiastic cyclists completed a 70km cycle.
Notable rides were from Roland Neururer and Lucy McDonald, who smashed the course with an average speed of 34.1kph, and also smashed everyone else, who all completed the course in their own time.
Keep an eye on Alyce Edwards, who is currently training for the 160km Lake Taupo challenge in November and will no doubt enjoy tomorrow’s challenge.
