I have bought my garmin 530 and has a theme for make intervals.
Near my house there is a road with about 1 km of free trail (road) for making intervals. I made 1X5

1 min very fast and 30 seconds resting and do that 5 times.

any other recommendation? unfortunately no more space to do more kilometers long distance.
