what pace should a fartlek be

If you’re not sure, just eat a large bowl of baked beans the night before and save up the gas as a turbo boost for the on’s. When you finally spring an oil leak you’re done.

Why do you call that "fartlek?"

Swedish for "speed play."

Your fartlek workout is whatever you want.

Start at 10k effort, then increase to 8k effort, then increase to 5k effort.

I would start with current fitness effort. These are workouts that are easy to "overcook."

Don't be a workout hero.

2/10

Focus on effort, but start slower on the first 2 reps than you think would be necessary. Last 4 will be your true working reps. By the 3rd rep your breathing should be labored, your legs should have a little burn in them but you should still feel strong. By the 5th and 6th you should feel like your hanging on, but could go faster if needed with energy in reserve. I wouldn't cook this workout too hard such that it detracts from your overall mileage, but it should definitely be harder than your easy runs.

Once a minute on a really good day. Stink everyone out

What should it be called?

something that doesn't sound like fart-lick

It should be fast enough to make you fart. If you didn't fart you didn't run fast enough, or maybe you didn't run fast enough. Hope that helps.

Correction: maybe you ran too fast.

Interval session

Yes, this is the answer… a fartlek should not be structured… run fast for a little bit then run slow for a little bit then run fast to the next tree or house or whatever then jog and look around at the birds then run fast then run easy… no structure just run baby!

That's not a Fartlek. It's an interval workout. 'Fart' in Swedish means 'speed' and 'lek' means 'play'. Then you get Fartlek= speedplay. Original Fartlek is totally without structure. You might run fast to a telephone pole or a tree and then jog a little and then make a short burst again . A funny way to train when you sometimes get tired of structured intervals.
