Half marathon in 8 weeks?

I run 2 miles every week or so- so not much but I workout five days a week and have run 5k/10k in the past.

I decided to sign up for a good cause donation half marathon but I only have 8 weeks to train. Lol. I’m not looking for a great time- just advice on how to train for a long race in such little time when I’m not a daily runner.

Thank you!
