WILLIAMSTON, S.C. – The Maxxis 4-Cycle Sprint Series is less than one month away from its 2021 season opener April 9-10 at the high-speed 103rd Street Sports Complex in Jacksonville, Fla., where 11 classes will be offered between seven Briggs LO206 and three Vintage divisions plus a Kid Kart class.
The Maxxis Sprint Series weekend schedule differs from many national sprint touring series as many of the series’ events, including the Jacksonville opener, are two-day affairs with practice Friday and all racing taking place Saturday. This structure gives racers and families the opportunity to take all of Sunday to travel home and more comfortably prepare for the upcoming work and/or school weeks.
Entry fees are very reasonably priced at $80 per class and $50 for Friday practice. Transponder rentals are $10 for the weekend.
For Jacksonville, Friday, April 9 will see a full day of practice from 9am to 4pm that will include at least five rounds for all divisions. Before kicking off the 2021 race season Saturday, officials and competitors will take time Friday evening to enjoy a dinner and awards ceremony for the series’ 2020 class champions, top points finishers and other special awards recipients. Tickets for the dinner and ceremony are only $10.
Action will start bright and early Saturday morning with gates opening at 7am, drivers meeting at 8 and one final round of practice at 8:30. Lap times from the morning practice will set the lineup for qualifying later in the morning. Both the morning practice and qualifying will be 4 laps in length.
The seven 206 classes will each run two heat races while the vintage divisions will run one round of heats. After the first round of heats, vintage classes will run their 10-lap mains while 206 classes will be running their second round of heats. After the second round of heats and vintage main events, the 206 classes will hit the track for their big main events to conclude the race day.
Each round of competition is progressive from the previous round meaning that the position a driver finishes in qualifying is where he or she will start heat one, and where a driver finishes in heat one is where he or she will start heat two or the main event, depending on the class.
