Didnt go last year, but 3 off us are booked for this year. To get to the track seems fairly straightforward (in Russian terms) cant remember the names of the stations, but it goes something like this ( can find the detail if you require) Metro first then switch to Train (cant remember name of the station) then train out of the city (North) then they do free shuttle buses from next Station to the Track..
( Helps if you can speak a little Russian and understand the Metro system tho!)
Like I say can get the detail if reqd.... or Google it.
