Audax Altitude Award
points are given to hilly events meeting certain criteria that requires a PhD in head scratching to understand. Simply put you get 1 point per 1000m of a qualifying event; points are refined into 1/4s. Sometimes a section of an event may qualify giving it AAA points even though overall it has less climbing than a similar distanced event that has 0.00 AAA points...
Within this there is a ranking system for events less than 300km.
Silver Grimpeurs lie in a small indestinguishable band between Bronze and Gold and can often be the difference of just one hill.
