Running

I quite enjoy a bit of sub zero. 2009 in Edinburgh was excellent and I discovered that XC spikes are pretty good for running on compacted snow in the city. Getting out into the Pentland hills was quite spectacular.

@Dammit re treadmills: I have an acquaintance (also s London based) who does a lot of hill running and he does uphill tempos on treadmill. I shall ask where for you. But are there no hills near you? Crystal palace/ forest hill maybe?

There are plenty of hills where I live, however what I am looking for is the ability to run a half marathon distance at a steady 8-9% incline.

Not often, but probably once a month or thereabouts to check how fast I can do it.

Sadly none of the steeper hills around here are 21.1km long.
