Why the 1:45 half target?
Why does the 3:45 schedule suggest a 1:45 half is needed? All the race-from-race predictors suggest a 3:45 marathon comes off a 1:48 half.
I'm not sure why I mind having just done Fleet in 1:44:16, but I guess would like to know if I have a bit of "fat" in my 3:45 target!
I'm sure this has been discussed elsewhere but I won't be able to find it!
Because 1:45 is a rounder number than 1:48? Because there's a bit of leeway in it? Or possibly because the whole prediction thing is guesswork in any case, particularly trying to relate it to any given individual?
A friend of mine was good for a 1:35 half but struggled to break 4 hours for a marathon, whatever he did in training. Likewise I'm sure there are plenty whose marathon PB is only just over twice their HM PB.
That said, Fleet in <1:45 should set you up for a 3:45 marathon, assuming you've done the long runs and don't do the first half of FLM in 1:45!
We're all different.
If your endurance is generally better than your speed (eg. if older or female), I think you find your half pace is closer to your marathon pace than if you're better at speedwork. Just a hunch.
Really suprised at this. I've checked calculators but I am a little sceptical.
Recent half - sub 1h40m (Berkhamstead - very hilly) Recent 20m 2hr50m (Oakley - undulating)
RW calculator 3h 29m from the half time, and 3h 46m from the 20m time
Maybe this is down to the type of training I've done - possibly need more longer runs....... a bit late now for VLM
My plan is to start moderately for the first half and then go faster in the 2nd.
Don't want to die in the last 5 miles.
hi guys, could you help me out. are you supposed to pick a pace and stick to it in Yasso 800, or go all out on each one and toke the average?
the first I think - in general intervals / reps are supposed to be done at a consistent pace.
hello achy leg i ran brentford half in 1.35 then ran the shakespere marathon in 3.42, both pretty flat races. i think everyone is different my 10k is 43 mins not great, i run halfs better.
I've got a HM pb of 1h35 ( 2 months ago) and a lot of the predictions put me in the 3h20-25 bracket but I am playing in safe and aiming for a 3h30 half. I think the predictions need to be taken with a pinch of salt. In my half marathon I was really pushing the pace all the way and working hard, in the marathon I want to be running at a comfortable pace that doesn't make me feel as if I am pushing and I've found an 8 min mile pace to be that
Depends on how much time you have got to do quality training.
