Half marathon under 2 hours

[Travelisfun]

I completed my first half marathon in December in 2 hours 29. Since then I have been doing around 3 4km runs (speed of 5.30/km) a week with the occasional 6/10km run.
I went on a 7km run today in just under 42 minutes (6 minutes/km). I have signed up to another half marathon in 10 weeks. Do you think it would be possible to get under 2 hours given how long it took me the first time?
I am unsure if I am being unrealistic with my goal!
Thank you :)

I think you might struggle to break 2 hours this time. But who cares, you'll almost definitely get a PB and then carry on training toward a sub 2. Good luck.

Since writing this post I am now going to try and run it in 2 hours 12!! 6 minutes per km is my aim, but if I don't get there I guess that is another reason to sign up to a half!!
I have been trying to run at least 5km each run, and am trying to vary my runs... fingers crossed I can do it!!!

@Travelisfun
i know this is very old but I wonder how you got on

i’m 45 and recently did a HM in 2h09 which I was very pleased with and wondering how I can improve on that next year and possibly get under 2h again

I did do a HM in under 2h once (1h55), many years ago, but was training very seriously for months on end and probably the fittest I’ve ever been in my life. I suspect that will remain my best ever race by some margin.
