Intervals aren’t for everybody and can be very hard work. However you shouldn’t be scared off completely as they can be very beneficial.
Try running with a group of friends and vary the type of intervals you run and the terrain. Try running fartlek as a group, taking it in turns to dictate pace and duration of intervals to add variety and the element of surprise.
