How are you balancing recovery time and managing such high mileage?
I’m trying to get one longer run in each week, but still want to do 3/4 a week (including the long one). For example, I ran 12 miles on Saturday but then didn’t run again until yesterday (10k) as my legs were still feeling tired. I ran again today (5k) as I wanted to do something but not tire myself for my longer weekend run, but it was definitely a slower pace today.
Any advice?
It's just a case of building up to it slowly...
When things are normal I average around 40-45 mile weeks, with the odd sporadic "high" week if I'm on holiday or off work, etc. So the stamina is there.
But you have to build to it slowly... I was fortunate to be quite fit when I started running properly, as I came from another sport and was already running perhaps 20-25 miles a week. But it still took maybe 6 months of slow progression to get up to 40 miles.
With regards to doing 70... I find there's three elements which affect my mileage.... Training, racing, and work. I can usually do 2 out of 3 of them hard...
Example in normal circumstances, I'm working in office 40hrs a week and racing most weekends, so I have to be careful with my training mileage and can't get above 40.
But presently there's no races, and not travelling for work, so I can push a lot harder in training and do two sessions a day.
Advice...
Build up slowly. There rule of thumb is don't increase your weekly mileage by more than 10% each week or you'll run into trouble.
I'd also add consideration as to how hard you're running. If you're doing hard "sessions", reps etc, they take longer to recover... I don't run "hard" more than twice a week, the rest is steady mileage...
Other thing to remember is I'm training for long fell (mountain) races... Some of these can be 5-6hrs for a 20-25 mile race. So what I'm doing is not necessarily ideal for everyone (it's possibly not even ideal for me!)
Obviously if you're training to run a better 5km/10km/half, you can likely run less, but a bit harder. But I'd be surprised if the very best marathon runners aren't still doing 80-90 miles per week (probably a lot faster than I'm doing them too!)
Main thing is don't suddenly jump from running twice a week to 7 times a week. It won't end well!
