You can get from the MCC station to the Congress center by bicycle. You are allowed to take your bicycle with you in the MCC. It is free of charge.
Be careful: Volgogradsky prospect is not the most convenient place for cycling. After the overpass over the railway tracks along the road there is no pavement for about 250−300 meters. On summer photos it seems that it is possible to pass, but in the winter time it is most likely that all the space will be filled up with snow. We recommend to combine bicycle with the public transportation!
Here is the map of how to get from the MCC station by bike.
