We've said it before and we'll say it again: This is a myth for the vast majority of modern cars. The 3,000-mile oil change is the credo of the quick-oil change industry and dealership service departments, designed to regularly get you into the service bay. (Jiffy Lube recently abandoned its advocacy of the 3,000-mile rule, but clings to severe-schedule advice with which Edmunds disagrees. More on this later.)
Blenheim Palace Triathlon. Youâll have to be quick if you want a place as this event sells out fast â and for good reason. The amazing setting and beginner-friendly lake swim combine with two distances â super sprint (400m swim) and sprint (750m) â for a truly memorable first triathlon.
Usually if two or three of the three triathlon sports is below sprint distance, you can call it a mini sprint. These two plans will train you for a triathlon with these distances: 1  400 yard swim | 8mile bike | 1.5 mile run.  400 meter swim | 13 kilometer bike | 2.4 kilometer run.
