The Subaru MTBA National MTB Series is on again this weekend, and although the downhill racing will take place in Thredbo, the cross-country racing will be on at Mt Stromlo, with Short Track (XCC) on Friday afternoon 6th February, and the Olympic Cross-Country (XCO) on Saturday 7th February.
Entries are closing on Monday evening (today!)
There are a couple of hard parts, most notably the Cardiac Arrest climb followed by The Hammerhead. This video on YouTube by Oliver Armstrong is the best visual summary of the course. Take a look.
