Did a trial run of next years 25 mile round commute today, was quite happy with the 1hr 5 mins cycling in, and the 1:20 coming back, considering i was knackered on the return. 12.5 miles on a hybrid wasn't something i thought i'd ever end up doing for a commute each way.
That's a cracking commute. Perfect distance IMHO.
It's great that you are starting now as come the spring when the weather is much better, you will be flying.
An early morning commute in warm sunshine is one of lifes great cycling pleasures.
Please keep us updated as to how you get on.
As someone who does a long commute, can I offer some good advice.
Check your tyres after every ride. Dig out anything that's stuck in the rubber.
It's a pain in the arse but you soon get into the habit and it's less of a pain then getting a puncture.
