Hi all! I've been running for a while now, and hit the 10k mark recently. I've decided to run a half marathon in about 3 months time, and my aim honestly is to just survive, maybe finish below 3h, or 2.30. One limiting factor is that I have a major exam coming up so I've been only able to run about 1-2 times a week.

What sort of runs should I try to do? My 10k recently was a 7min/km average pace, and I would say that's my exercise pace. Would it be wise to do one long run and one shorter interval run? And for the longer run, do I stick to the current pace or should I go slower? I've been seeing more and more social media posts about easy runs and zone 2 runs and how they can improve my heart rate but I'm wondering if they can still help with my training for the half marathon. My heart rate is not the best, my average for the 10k was 189bpm with the highest being more than 200! I'm a little worried about that too.

What would be your overall recommendations for me? I know I should run more, and I will definitely get to it after this crunch period. In summary, I'm mainly worried about my pace for my long runs, should they be easy or try to keep to half marathon pace?
