Preparing for a 95km race?

So I've been guilted into entering the local 94.7km.... The furthest I've ever ridden was around 25km, and that was five-six years ago! The race is in about six months. Any good websites which could breakdown a decent training schedule?

I'm overall pretty fit, but cycling is a different animal...

RAF I'm afraid I don't know any sites but personally I'd suggest doing it in increments

Start off doing say 10-15km a week, then the next week maybe take that to 15-20 km and so on and so forth

A few of my friends use apps like Strava, and sites like www.mapmyride.com to track their progress.

Is it a "race" or some sort of charity ride pub crawl? For both you'll need to get some miles in but, if it really is a race, then you'll be needing train in groups-ideally-and certainly will need to be riding at pace. Is it hilly? This is another factor.

It's a legitimate race, but I've been told I'm riding for charity. That said, I'm not the sort to amble along a race. Want to finish upper field, or at least decently placed among the amateurs.

As for the hill, Johannesburg is pretty hilly, a few guys from the local athletics club ran the Boston marathon, and didn't know where on heartbreak hill until they passed it. I don't know the course outlay, but I'm pretty sure there isn't a stretch of road in Jozi which doesn't prelude a hill.
