How many days would it take you to run 26.2 miles at 4:34 pace?

Not sure how many recovery days I’d need trying to do 10 x 50m sprints for 84-ish days. The epsom salt calculation would be another matter entirely.

one month

if one workout day followed by 2 days recovery

If I was trying to do that I would structure it as the 100m reps and do 30 at a time with slow walk recoveries or a few mins. Do that twice a day. So it would take 7 days. I do the extra two on the last day as a celebration.

50m reps would 8.5 seconds of running.

If you did 50m reps with 60s recovery. The entire rep & recovery would take 68.5s.

42.2k would be 844 reps.

844 x 68.5s = 16.05 hours

I actually think I could do this pretty comfortably.

I think I could run 211 200ms in 34s within 2 days. Probably within 20 hours starting at night/finishing in the morning.

Think of it as a weight lifting exercise.

Weight lifters will do 3-5 sets with 6-20 reps of a particular exercise and be within another set of breaking down. You're going to need more recovery somewhere around 300-400 reps. I'd guess the body would need at least three days for the muscular strength/endurance to do all the reps.

That is unless you're already a 2:30 marathoner, which since this is Lets Run, you probably are.

Forever bc I can't even sprint that pace.

I'd start with 4 to 6 reps of 33.3m under 5.7 seconds, take one day off, and repeat. (I'm doing 4-6 reps at 5.0 seconds now so that should be doable.)

After three workouts, I'd increase the volume to two sets of 3x33.3m with maybe 30 minutes between sets. If I warmed up and didn't feel I could hit the pace, I'd take an extra day off.

I'd probably get injured in the process so I'd need a week off somewhere along the way so it would take maybe 30 days.

About 22 years.

My normal stride session is 8x100m around 15-16 with full rest. I could probably get a mile very easily in under 20 minutes.
2 days for me

I'd have to do it in a pair of Jordan 4's on a basketball court.

Baseline to free throw line & back

Baseline to 3 point line & back

Baseline to 1/2 court & back

Etc

A few of those everyday for a couple years.

33.3m sprints from a standing start or out of blocks? Because rolling starts would need to include the average over the total distance, including the roll-into and the distance required to slow down, making the total speed of the sprint greatly reduced.

Nope. You have to include the total distance you run, meaning the distance required to slow down after your strides would greatly pull down the average pace covered.

You probably could but over 16 hours on your feet would be like an ultra. Although I suppose you could lay down between reps. I think this may be more taxing than we realise, but you could be ultra fit!

I think 150-300m would be easier. All that acceleration would take too much out of you. In the end this comes down to how fast this pace is for you .

I did a 4 min mile a couple years ago via 16x100+. Not easy. I think 8x200 would be easier especially with the friction from starting and stopping.

Slowing to a 4:34 pace... I think I could do it in 3 days

easiest way mentally would be to go 10 x 400m in 68 with full recovery, taking each one as easy as possible. Might manage two sessions per day without wiping out.

However, I'd almost surely get injured before 5 days was up.

On another note, it's high time to switch the whole thing to 100 laps. 40k. And enough of this mile-pace business!

assuming that's around 1500 pace for a lot of people, you could do 20x200m at that pace every other day, meaning it would take 19 days, but realistically, someone who had 4:34 as their 1500m pace could do a lot more than 20 200's at that pace every other day, so probably 8-10 days, but they would need lots of recovery after
