Excitment is building in the Senior Vet 40+ division with Ant Rountree, event organiser Shayne Wainhouse and Mike Gilbertson filling the top three places.
While youngster Seth Reardon may be out of contention in the Senior B all-in grade after a DNF in round one, he will make life interesting for the series leaders.
Reardon is new to the grade this season and is probably better known for his deeds in Enduro racing.
Last season Reardon won the national and central region Enduro junior titles, but he is certainly no slug at the motocross discipline.
The cross country track has been modified slightly for this weekend to make allowance for all the rain that has fallen over the past week.
The junior track will now be about 12km and the senior track 15km.
The changes have removed the swampy sections and a number of slippery downhill sections and left a course that is still rideable by all.
The Minis track has been shifted to a paddock closer to the pits and will consist of an undulating course of about 2.5km.
Points gained by club members in the Cross Country Series will be combined with points gained during the club's MX series (four rounds) to determine the "Wanganui Dirt Rider of the Year" award.
The two cross country rounds have double points compared to the MX races.
