My brother has challenged me to join him in running the Sarn Helen Hill Race (a 16.5 miler) in May, and the Snowdonia Marathon in October.
These are both fairly long runs, mainly off road, in hilly country (thankfully, the Snowdonia marathon doesn't actually ascend Snowdon itself). They're both in Wales - so those hills are going to be properly steep.
16.5 miles is what I call a "kilometrathon" - it works out at just over 26km. It's one of my favourite distances: long enough to be tasking, but short enough to stay fun all the way.
The marathon is a distance I've never actually raced, except to carry on for longer afterwards. I've run it solo a couple of times. I find marathons to be very tiring by the end, but again, they're the sort of epic distance I enjoy.
Anyway - all this is just to say: I'm getting back out there on the hill training again. Welsh hills are likely to be harder than the Marlborough Downs, so I need to put in more regular effort.
I also know that I need to strengthen my knees for the long distances - so I'll be doing some balancing and light weight work, too.
