I'm hoping it might be possible for a little advise and perhaps some perspective.
I race mountain bikes at a high level, but I am considering a new challenge and thinking about a marathon.
I run 1-2 times a fortnight, only up to 40min or so, both on and off-road. I can hold low 4min km for a time and my longest ever run was an off-road 1/2 in 2hrs over 1 year ago. Normally I don't run over 8km.
Realistically how much training would I need to do in order to run a sub 3hr marathon and how long would it take me to get up to those distance?
Mathew - most sub 3 hr marathon runners would have a half time of 01:20 to 01:25. They would be doing 40 to 60 miles per week and most experts would say that it takes several years to build up the endurance necessary to perform at your potential for a marathon. There is nothing in what you have written that could give anybody any idea of your potential as even the half time was offroad and you give no indication of the touighness (ascent/descent) of that particular half.
Thanks for the responses. Sorry I didn't give much info, I'll give some more and also search out the 3hr training forum.
The half was the Endurance Life Gower in 2011. 21.5km with 600m climbing. It was my longest run ever and still to date. I've only ever run one 10km and that was about 2 weeks training and 42min.
I think I'd get sub 20min currently for 5km. My splits are about 4:10-4:20min/km on a pretty hilly 4.3km that I often do.
Is there anyone who advocates HIIT for running in a similar way to many do for cycling? Maybe 3hrs is a little too optomisitic, it seemed like a nice round figure.
Some pointers, first up you're probably being a bit too ambitious as a first goal (fewer than 2000 people in the UK ran it last year), but equally having a target in mind is a good way to keep yourself motivated.
If you want to get started you'll need to commit to running quite a few more miles. HIIT doesn't help too much with marathon training it's about consistent weekly mileage, with a couple of harder workout days a week.
3:30 would be a good target for your first, if you can already run around the 20min mark for a 5k you will be fine speed wise, what you need to do is work on your endurance and start getting your body conditioned.
I'd guess if you work at it you cold have a realistic shot at sub 3:30 in the autumn, then maybe look at reducing your time next year.
Thanks guys. 3:30 would be more realistic I think.
My problem with running is that I get bored. Off-road runs I find OK up to about an hour, a little more in an event. I'd still be cycling, so working out a good training plan would be tricky.
My endurance is fine, speed is what I am lacking although it is progressing slightly. Thats why I thought HIIT might be a good idea.
Just need to find an event to target now!
Marathon simply because its a marathon. It's only the bucketlist and if it goes well, hopefully the Norseman at some point.
Regarding endurance, I mean from a general sports background. CV and metabolic stuff.
