@cmonkey, there is no need for dedicated bike paths, just open road.

The best way to get into the long rides is to join a cycling club, they tend to know all the good local routes and riding in a bunch gives you extra 'ommph' thanks to the slip stream effect. You can easily cover a longer distance than you would solo. You'll need a road bike though, I turned up on a heavy hybrid for my first long ride, it was torture!
May Update
I was debating whether I would upload my analysis this month but realise that I need to be honest with myself about figures, and what better way to remain accountable than sharing your financial woes on the interweb

. If I'm not honest with myself, there's simply no point in collecting all this data. Frankly I've failed to save a penny in May

. In fact expenses exceed my income for the month

. In addition my dog has developed a leg injury, he's limping so looks some additional vet bills are likely later too.
Discounting the repayment of a significant family loan (my last unofficial debt), May wasn't such a bad month for expenses, I would have managed a 50% rate despite some
extravagant purchases including a new waterproof rear bike light, a bulk purchase of inner tubes (more cost effective, duh), a Kindle Paperwhite, £36 of books (for my holiday reading - all purchased used, or ebook). I also spent over £80 more on food than budgeted due a few takeout meals. That will teach me for not properly planning meals. I'm hoping to make up for this in the coming months with a ban on takeouts. It's really interesting to see the break down between essential food spending vs the cost of eating out, take outs and discretionary purchases (i.e. treat food I could live without).
It looks like my expenses are highly variable month to month, which really isn't a surprise. It will be interesting to see how it averages out when I have 6 months of data. I have already made the shift to buying in bulk and stocking up on certain goods. So some months I end up spending considerably more than others. One positive worth sharing this month is that I have been experimenting with baking my own bread, some of the loaves are hit and miss but occasionally I make a great one that is gone within a day! For the first time I have baked every loaf in the month rather than resorting to the store bought crap. Feeling pleased with myself about that!
Stay tuned...
