its 2 mountains and 1 hill in the middle (which i find the real killer that softens you up for waunfawer). i did the same thing, wouldn't do it until id broke the sub 3 mark. and haven't done it for a year or two because old farther time is catching up with me and best performances will soon be a thing of the past (hence why targeting pb courses)
I'm jealous that your doing silver-stone, so wish to do that one as I'm a fan of f1. but it clashes with 20m races that i only get a crack at once a year.
all the best which ever you decide to do and don't take race predictors too seriously for your first one. when you put other distances in they are notorious for predicting way too fast a times.mara's are not very forgiving beasts, and can make your first not the enjoyable experience it should be.
p.s. every welsh/eng mara runner should have snod on their cv, absolute gem of a race
in the smaller mara's i have the same problem being a sub 3 runner, although in the big city mara's i have trouble with runners getting in the way at the start. so its swings and roundabouts
i agree totally about the two races clashing and am disappointed that it has happened and hopefully this can be avoided in the future. personally i wish they had both gone for earlier or slightly late dates, instead of slap bag in the middle of the mara calendar, that time is very congested with excellent proven races. i'd like to support both my local mara races, but i'm not willing to invest 18wks training for a race without a proven track record of excellence (something neither has yet). i've only manged to fit chester in due to my decision to do a very late main race (27th nov), and its not gonna be flat out, more of a very hard & long, long run.
all the best for liverpool, quite a few club mates are doing it and i'm keeping an eye on it for the futer, and one i want on my CV. although when i can fit it in though is another mater. (but that in some ways is a nice problem to have)
