how hard is it to run under 70 minutes for half marathon?

0/10.

Prove it.

With your 5k time and some more mileage you should get it. You prob won't be able to hit 70 mins just training 20-30 mpw. The race is half your weekly mileage and you'll die the last few miles. You need to add in a 15 mile or so long run each week and increase the length of your tempos.

My wife runs 40-50 mpw and her PR is in the 1:50's. So on 20-30 mpw, you might be able to break 2 hours. But if you do somehow get close to 1:10, congrats. If it's any decent race, you might get a chance to try and outkick the women's overall winner.

Ditto. Prove it. I'm calling BS on the 5K with those splits. Where's the race results? And a track workout with rest intervals that sums up to 15:06 doesn't count. You claim you ran that for a 5K. How about 10K's? 10-milers? Have you ever even raced anything over 5K? I think you're seriously overestimating your abilities based on your mileage. You're going to go out in 4:50 thinking it will be a piece of cake, and struggle to finish in any type of respectable time. Typical high school inexperience at its best.

Did I call it or what CZ? 1:17:21. Pretty sad if that's all you could manage if you're as fast as you claim you are. How did that piano feel on your back the last few miles?

Guys i know who this guy is, he's not lying or anything. people have off days, they happen all the time.

Off days after you've bragged for months how you could easily break 1:10 even though you've never done a half before? That's hardly an off day. That's called overestimating your ability, a lack of experience, and an inflated ego.

Why so harsh? Everyone's a winner!

Mike Rossi can do it, and so can you

Is this for real? Have to say, that is talent if true. 1:17 on 25mpw?

This is lets run.com. It would be nearly impossible for any of us to run OVER 70 minutes for a half. I mean, that is basically hobby-jogger territory.

Meh.

I'm more impressed with the 5 km mile splits, if those are for real.

I went 1:14 more than a year after I completely stopped run training (however I was biking 40+ km/day to and from work most days that Summer). A few years later, I put in some really hard sustained training to see what my true potential was... apparently it wasn't as high as I thought as I only ran 1:09, even though I was averaging around 90 miles/week with 2-3 hard workouts. I'm always skeptical when somebody says that they ran a fast time off of very little running mileage because usually that person is either omitting the fact that they only stopped serious run training a short time ago or they cross-train like a fiend.

For me, I've found that, as long as I maintain my skinny build, spend a fair amount of time on my feet, and do some cross training, I can run reasonably close to my PRs without putting in much actual running work. Maybe for others it's different.
