scholarsgate….I work in the city and know that area well I was part of the team that built the new road that goes right past the velodrome…your best best is to stay in one of the city centre hotels and just commute out to the site
if you drive there is a big on site car park
if you dont drive or want a drink then get the train from either Glasgow central or argyle street low level to Bridgeton and its a 15 min walk from there
But be aware the area in which it has been built is one of the crappiest parts of glasgow (the idea it to regenerate the area) so there is nothing in the surrounding area and any pubs or cafes are proper dives not recomended for tourists…..so after the event head back to the city centre
