The country's top junior and senior athletes will take centre stage over the next four days, starting today inside the National Stadium, as the JAAA National Junior and Senior Championships get under way, with places on several teams to international events up for grabs.

For the seniors, the main target will be the Commonwealth Games in Glasgow, Scotland from July 23 to August 2, while the country's leading juniors will be aiming for selection to the World Under-20 Championships in Eugene, Oregon from August 5-9. Athletes will also be competing for spots on teams to the Pan American Championships, NACAC Under-23 Championships, and the CAC Games.

Action will get under way at 9 a.m. with the qualification round of the men's 100 metres. The six fastest athletes will advance to the preliminary round to join 25 other competitors later in the day at 6:10 p.m. The organisers have made an adjustment, as action will be on the backstretch where athletes will run with the wind to aid in facilitating faster times.
