The morning session features qualifying in women's Pursuit for riders in classifications C1 to C5, followed by the men's Individual Pursuit for B classification riders, with finals for each in the afternoon session.
The first test of the crowd's noise-generating capacity comes with the first medal on offer right at the start of the afternoon - the men's Individual 1km Time Trial for riders in classifications C1 to C3.
Host Nation hopes rest with Mark Lee Colbourne in the C1 category and C3 rider Darren Kenny, but Rodrigo Fernando Lopez of Argentina (C1) and Xie Hao of China (C2) are world champions and showing strong form.
Kenny and Xia are world record holders in their classifications, with unfactored times of 1:08.668 and 1:18.728 respectively.
Arnold Boldt of Canada said after a training session in the Velodrome today: 'It is beautiful. I can tell it is going to be noisy. I can hardly hear myself now but I think we will see some PBs tomorrow.'

'Much of it is psychological. We have good coaches, physios and the cycling team. We are ready; we can't do any more,' he added.
The Australian women dominated the medal table in the Individual Pursuit at the World Championships in February, taking three of the five gold medals. China's Sini Zeng (C2) and Great Britain's Sarah Storey (C5) took the remaining golds.
The threat to those champions comes from several quarters, particularly Netherlands and USA.
The men's Individual Pursuit B finals close out the day with the tandems in high-speed action. Bryce Lindores, 20, from Australia, piloted by Scott McPhee, is world champion.
His nearest rivals are Irish rider James Brown, Daniel Chalifour of Canada and Miguel Angel Clemente Solano from Spain.
