no, but you're gonna be exhausted
just curious, Why are you going from doubles to singles? doubles are almost always better during the base phase
depends on what kind of volume he is at now. 70 MPW in singles is doable. 100 not so much.
I've peaked at 75 miles this summer in 4 doubles/week. But now I'm switching to singles and was worried that I'd lose fitness. A lot of my 4-5 milers are going to become 8-10 milers now and I'd like to keep the same pace. Everyone here always talks about the benefit of running twice a day though.
Stick with the doubles. If anything work in more 8-10 mile "main" runs and keep extremely easy 30 min doubles 3-5 days a week. If you stick with them you should see some great improvements.
Yes, you idiot.
If you can handle running singles do it.
75 miles in 7 runs is generally better for you than 75 miles in 12 runs, so long as you are still getting proper recovery (less of an issue during base since there aren't any killer workouts and races are fewer)
The big advantage I see in doubles is they get you moving twice a day and help promote recovery at a higher mileage. If you are in a phase where the role of recovery is de-emphasized somewhat, running singles would be preferable, as there is training stimulus in the 8-11 mile range that simply is not there in the 3-5 range.
If you are running 75 in singles and absolutely grinding it out then you aren't doing yourself any good, and should definitely be doubling at that mileage, but if you can maintain a good training pace, get in some hills, a road race here or there, then I would suggest singles.
I will say, from personal experience, if you are running 75 in doubles, it is NOT an easy matter to just flip the switch to 75 in singles. 75 in doubles probably means your longest 7 runs total around 55-60 miles, and you need to recognize that, and move the mileage down a little as you transition into singles.
There is a bit of a personal aspect to it, but I would say for most runners, working toward running their current mileage in singles can be as beneficial as pushing their mileage a little higher in doubles, especially when you get to a point where training time becomes limited. If the question ever becomes "Miss sleep to run X mpw in doubles, or run X-10 mpw in singles" ABSOLUTELY run singles. The single most beneficial non-running thing a runner can do is get more sleep.
Hopefully you got some help out of that, happy training.
No, but two women are always more fun than one.
