Main Street will be closed from 5 a.m. until about 11 a.m. between Del Valle Parkway and Neal Street to accommodate the runners.
The Rotary Father's Day tradition has continued to grow as runners, their children and families participate in either a 10K run or 5K walk or run, as well as Kids' Challenge races.
The 10K run will start promptly at 8 a.m. under the Pleasanton Arch, followed by the 5K run at 8:20. The courses wind through Pleasanton neighborhoods, the Alameda County Fairgrounds and on trails along the Arroyo del Valle.
Traffic also will be slowed by partial lane closures along the race courses, affecting part of Valley Avenue, Paseo Santa Cruz, Del Valle Parkway, Division Street and St. Mary Street between 7:30 and 9:30 a.m.
Three separate Kid's Challenge Races, for children ages 2-8, include a number of 100-yard dashes on Main Street, finishing right underneath the Arch.
Trophies will go to the top male and female finishers in designated age groups.
Registration will take place in the Round Table Pizza parking lot starting at 7 a.m. Sunday. Fees are $40 for adults and high school students; $30 for those in elementary and middle school; $15 for ages 2-8 in the Kid's Challenge, and $30 each for families of four or more.
Proceeds will go to support the Rotary Club of Pleasanton's scholarship program as well as Hope Hospice, Rotaplast, Tri-Valley YMCA, Valley Humane Society and victims of the Boston Marathon tragedy.
Beautiful etched-glass trophies will be awarded to the top male and female finishers, as well as the first-place male and female Masters (over 50 years old) winners. In addition, medals are given in designated age groups for both male and female participants. Each child participating in the Kids' Challenge will receive a finisher ribbon.
Check-in and race-day registration opens at 6:30 a.m. in the parking lot of the now-closed Round Table Pizza restaurant on Main Street.
