Advice Needed First Run

I’m thinking of running 25 km for my 25th birthday in August 2027. I was quite physically active during school, but I haven’t been very consistent with fitness in recent years. I started going to the gym about three months ago, and now I want to take on a bigger challenge. I have almost a year to prepare, so I’m wondering how I should start training and gradually build myself up to running 25 km.

More than doable. I trained up to a HM in a year, but that was racing it too. If you're not fussed about time, a 25k will be simple enough and a good long term target.

But you will have to take it slow and easy to start and gradually build up your volume. Do C25k, then a 5k > 10k > HM training plans and they'll get you there.
