Menlo School graduate Maddy Price saw her highly successful season extended to the end of the month after capturing the women's 400 meters at the Canadian Junior Track and Field Championships on Saturday in Sainte-Therese, Quebec.

Price, who came into the meet with the No. 2 time for a Canadian junior, ran a lifetime best of 53.20 to win comfortably over top-ranked Christian Brennan. The University of Oregon sophomore clocked 43.47 for second.

Price's previous best was 53.42 while taking second at the CIF State Championships in June.

Both athletes are expected to be named to the Canadian team that will compete at the IAAF World Junior Championships, July 22-27 at the University of Oregon.

Price will attempt to qualify in a second event, the 200 meters, on Sunday. The prelims will be in the morning followed by the finals later in the day. Price also could be named to the Canadian 1,600-meter relay team, based on her winning effort in the open 400.

Price qualified for the 400 finals by clocking the fastest time of 54.51 in the prelims on Friday.

The IAAF World Junior Championships is set to be the biggest IAAF event ever to be held on U.S. soil.

In terms of athletes, the biggest ever World Athletics Series event hosted by the U.S. was the 1992 IAAF World Cross Country Championships in Boston, where 580 athletes from around the world competed.

Based on member federations, the biggest WAS event to be held in the USA was the 1987 IAAF World Indoor Championships in Indianapolis, where 84 nations took part.

But this year's IAAF World Junior Championships is set to surpass both of those marks, as 177 member federations have expressed interest in the championships, with 1,758 athletes provisionally entered.
