Over the years, when sani2c became so popular it would sell out immediately, the event grew and was split into the Adventure and the Race, with the elite racing being part of the Race. The Trail was added in 2012 when entries for the Adventure also became hard to come by. In 2020, with a postponed and paired down event happening in December due to COVID-19, the Trail was dropped, but now it makes a comeback as the event that will cater for e-bikers.
KAP sani2c has welcomed e-bikes to enter sani2c for several years, and from 2024, the Trail event will be the e-bike race, with a podium and leader jerseys, and e-bikes will not be allowed to enter the Race or Adventure events. Conventional bike teams may join the Trail, which will facilitate mixed parties of e-bikers and conventional bike teams. This shift will mean that e-bikes are well catered for and feel welcome at sani2c.
