Dame Kelly Holmes admits she is stepping into the unknown when she runs in her very first London Marathon on Sunday.The double Olympic champion will line up alongside 53,000 amateur runners in the 26.2-mile race, more than a decade after she stopped competing as a middle-distance athlete. Cricket girls get Holmes vote Englands 2009 cricketers are Kelly Holmes pick of 25 years of Sky Sports coverage Last year, I went to the London Marathon to support two friends and I just found the environment, the energy and the atmosphere around it just amazing, Holmes told Sky Sports News HQ. So I combined the challenge of running a marathon with the challenge of running for five charities and raising £250,000. Dame Kelly won two gold medals at the 2004 Athens Olympics I have been trying to blank it out but everyone keeps wishing me good luck for Sunday!Im a bit worried about whether Im eating and drinking enough, its more the whole preparation because I have no idea of what to do. Sally Gunnell sent this message to Dame Kelly Homes ahead of the London Marathon this weekend. But the first thing is to get round. Im under no illusion that it is a long way and it will take a toll on my body. I think I can run under 3hr 30 mins, probably a little quicker, because I have an idea about what my average pace will be.I think I will need to control myself but the thing I am most looking forward to is that finish line.Dame Kelly, who won 800m and 1500m gold at the 2004 Athens Olympics, is raising money for Myeloma UK, Mind UK, Hospice in the Weald and the Pickering Cancer Care charity. Dame Kelly established the Trust in 2008 She is also raising funds for the Dame Kelly Holmes Trust, established in 2008 to help get lives on track by using world class athletes to engage, enable and empower disadvantaged young people.One of the athletes representing the trust is British and European kickboxing champion Ruqsana Begum, who fights Swedens Susanna Salmijarvi for the world title on Saturday.I was fascinated with the work they do with young people who just need a little bit of guidance, Begum told Sky Sports.The Trust run education seminars and workshops using top-class athletes to talk about their journeys in the hope that it inspires youngsters and helps them believe that they too can be successful in life. Kickboxing champion Begum says the Trust has allowed her to give something back I have been blessed to come this far in my career and it is so important to give something back.Kelly is so down-to-earth and so humble and its great that she set up this project because her name brings a lot of awareness and attention to what the charity stands for.Kelly is such an inspiration and was one of my first role models. I remember watching the likes of her and other powerful athletes like Tessa Sanderson as a young girl. They really attracted me to sport in the first place. I know she is going to do the business on Sunday.Also See:SportsWomenLatest Show NewsLatest NewsSportsWomen VideoCameron Maybin Yankees Jersey .

Through five games, its marginally improved.The No. 18 Gators rank 77th in the nation in total offense after playing a relatively soft early schedule against Massachusetts (75th in total defense), Kentucky (108th), North Texas (99th) and Vanderbilt (73rd).Florida (4-1, 2-1 Southeastern Conference) finished with a season-low 236 yards in a 13-6 victory at the Commodores last week, a pedestrian performance that has become somewhat routine in Gainesville.The Gators will have to wait a week to see if they can fix their struggling offense since Saturdays game against LSU (3-2, 2-1) was postponed because of Hurricane Matthew. Florida hosts Missouri on Oct. 15.The Gators should get quarterback Luke Del Rio back. Del Rio missed the last two games because of a sprained left knee. But even when Del Rio was on the field, Florida was far from explosive.The Gators managed 10 points through three quarters against UMass in the opener and then 19 points through three quarters two weeks later against North Texas. So McElwain, who was hired to fix Floridas floundering offense, has failed to deliver through 19 games.Am I excited about where it is? No, McElwain said. Weve got to get better play at some positions, and weve got to get more energy out of those positions. And yet thats my responsibility.McElwain enjoyed offensive success at nearly each of his previous stops, including recent stays at Fresno State, Alabama and Colorado State. But nothing has been easy in two year at Florida.Quarterback play has been a major issue, with McElwain starting Will Grier, Treon Harris, Del Rio and Austin Appleby. The Gators ranked 112th in total offense in 2015 and were mostly awful down the stretch, scoring two offensive touchdowns in the final three games last season.Having no consistency at the QB position has been problematic. But its hardly been the only concern.Florida has one proven playmaker at receiver, Antonio Callaway. Carries are shared amonng four running backs.dddddddddddd Theres trouble creating holes and providing protection up front.Floridas offensive line was humbled at Tennessee and Vandy, taking a step back after showing some progress. McElwain challenged the line to play better.He just wants to see us be great and he knows how good we can be, center Cam Dillard said. The team goes as we go, so we take that on us. Thats part of the job at the University of Florida. You come here and youre supposed to take care of your job and do what you need to do.The Gators have two sophomores and a true freshman starting on the line, but McElwain doesnt want anyone using that as an excuse.This whole young offensive line thing, Im over that, McElwain said. These guys have played enough.Florida wants to establish a strong ground game, forcing opponents to play more defenders near the line of scrimmage and then gaining big chunks of yardage with play-action passes. It sounds fine in theory, but if the run game gets stuffed, then what? The Gators arent dynamic enough at quarterback or receiver to look anything like the Fun `n Gun that once defined the program.Since clinching a watered-down Eastern Division last season, Florida has averaged 21 points while posting a 6-4 record. Thats comparable to Will Muschamps final 10 games in Gainesville, in which the Gators averaged 27 points and went 5-5. Muschamp was fired for losing games and not scoring enough points.The Gators believe McElwain will get the offense turned around. But when and if it happens is unclear.Do I have crystal ball? No, McElwain said. Did we do with what we have based on our team as far as some ball control and playing long field to give us an opportunity to win ball games? I think we did. Thats part of coaching -- know what you have and keep pushing to get what you want.Weve done a pretty good job of playing team football.---AP college football website: www.collegefootball.ap.org ' ' '
