Both riders have followed their own paths to Saturday’s event at CenturyLink Field in Seattle in order keep their competitive edge heading into the start of the final three races of the season.Tomac, who is in the thick of his defense of the 250SX West title, raced a handful of times on a 450 before resuming his training routine aboard the 250 he has taken to four victory celebrations this year.Eli Tomac (GEICO Honda CRF250R Supercross) says: “It feels like I haven’t raced in forever. This last part of the season is like a fresh start to a mini-season for me. I’ve been feeling really good the whole time I’ve been off. I’m really looking forward to this weekend.”Tomac started the season off with three straight wins and will be looking to close the season in a similar fashion as he tries to track down 250SX West points leader Ken Roczen, who owns a 17-point advantage over second-place Tomac.Eli Tomac says: “The 450 kept me on the track racing as long as I could. It really help my confidence to ride against the best guys in the world. It helped me push harder and realize I have to make it happen, get good starts and not make any mistakes while I’m out there. I’m ready to get after it.”Osborne dealt with a bum shoulder for much of the first part of the season, which limited his effectiveness on the bike. Time has allowed that shoulder to heal with enough space in his schedule to get in some racing of his own.Zach Osbourne (GEICO Honda CRF250R Supercross) says: “It took two or three weeks to get my shoulder better. Once I was better, I decided to race some GNCC races. That went real well for me because I got on the podium both races I was in.“I did it as a training tool but it also gave me some good confidence and good feedback on my fitness. I’m going into these last three races really prepared and I plan on racing like I’ve got nothing to lose.”The break has also given Osborne the opportunity to get a jump start on the motocross season, which gets started in about a month.Zach Osbourne says: “I went back out to California and did a lot of outdoor testing,” he said. “It’s went really well for me. It can be an awkward time of year and it’s hard to get a good mix of Supercross and motocross training. I’ve just decided to get in there and put in as much work as possible.”Practice for Saturday’s Monster Energy AMA Supercross event at CenturyLink Field gets under way at 12:30 p.m. PDT with opening ceremonies at 7 p.m. SPEED TV will air the 250SX race at 5:30 p.m. EDT on Sunday.
