Add Desiree Davila to the short list of runners that would relish the opportunity to compete in the 80-degree-plus temperatures forecasted for tomorrow’s Boston Marathon.“I think it’s (the heat) on a lot of people’s minds, but in all honesty I like the tougher conditions and not because I’m necessarily better at them,” Davila said. “I think it’s distracting for other people. At the end of the day, everyone has to race in them. I’m kind of sad I’m missing out on a tough day. I think if conditions weren’t as favorable last year that it almost would have been a better day.”Davila is in town to compete in today’s BAA 5K race after running her way onto the U.S. Olympic marathon team with a second-place finish in 2:25:55 in January’s Olympic trials in Houston. The 28-year-old was a narrowly beaten runner-up in last year’s Hopkinton-to-Boston classic with a personal best of 2:22:38. She is currently in the speed segment of her preparation for the London Games and is looking for a good effort in the 5K. Davila is also looking to lower her personal 10K best of 31:38 on the track in the coming weeks.“It’s good to be back here in a competitive event and this race is a steppingstone for what I want to do in the spring,” Davila said of the enormously popular 5K. “I wanted to crunch in a speed segment and this is the perfect place to do it, and then go after a fast time on the track. The top three (today) would be great.”The women’s 5K field is as impressive as the marathon lineup with four runners who have personal bests under 15 minutes. Ethiopia’s Worknesh Kidane heads the field at 14:33, followed by Kim Smith of New Zealand with a 14:45. Australia’s Benita Willis has clocked 14:47, and Kidane’s countrywoman, Aheza Kiros, has run a 14:56.Ethiopia’s Ali Abdosh is the clear favorite in the men’s race with his personal best of 12:56. Ben True, the 2011 winner, is back to defend his title while Adrian Blincoe of New Zealand and Sam Chelanga of Kenya could be ready to strike in the final stretch to the finish.“I think this 5K is going to be quick,” said Chelanga, “I’m quessing around 13:30-something to win. It’s going to take a kick. It’s always like that.”Chelanga, who owns personal bests of 13:19 and 27:08 in the 5K and 10k, respectively, is looking to qualify for the Olympics in the 10K. He believes it will be the East Africans who emerge from the pack tomorrow.“I don’t think it’s going to change anything because they’re used to the heat and all that,” said Chelanga. “It’s going to be a challenging marathon for a lot of people.”After missing last year’s BAA Invitational Mile, 2010 winner Morgan Uceny is itching to be the first across the finish line again. Uceny is coming off a huge 2011 season where she was ranked No. 1 in the world at the mile and 1,500 meters.“Obviously that is the most important goal this year, to get on the Olympic team,” said Uceny. “This (mile) is a great way to open the season. I really like the road scene. The tight turns are what makes this race more tactical.”Australia’s Collis Birmingham has the fastest mile time in the men’s field at 3:54, with the United States’ Kyle Miller (3:56) and Tim Ritchie (3:58) also under 4 minutes. American Ben Bruce (4:00) and Ireland’s Adam Walsh (4:04) round out the quick field.
