British distance runner tackles the half-marathon at this weeks World Road Running Champs

Sam Harrison leads the British challenge in the World Road Running Championships in Riga on Sunday (Oct 1) and hopes to build on a terrific year that has already seen her run PBs of 30:51 for 10km, 67:17 for half-marathon and 2:25:59 for the marathon.

Its my first time in Latvia, so Im not quite sure what to expect, she says. Id like to run a solid time but it depends how the race pans out.

Im not sure the course is going to be super-fast so Ill probably try to go for a good position. Finishing in the top 10 would be amazing as itll be a tough field. But if Im capable of more once Im in the race then Ill push for it.

Her half-marathon best, which was set in Berlin in April, puts her No.4 on the UK all-time rankings whereas her marathon PB in London a few weeks later ranks her No.6. After seeing the words mostly flat on the course description for Riga, she is not expecting an amazing time this weekend but generally she hopes she has stepped up a level from the early part of this year.

After London she clocked another PB with 31:11.40 at the Night of the 10,000m PBs but after another 10,000m in Hengelo (31:37.97) she took a short break before building back into training in the past three months.

Trainings gone really well over the last few weeks and I even ran a 5km PB (15:11) at the end of August, she says. Going into a full track season wouldnt have been wise. I needed to recover a bit from the marathon as it took it out of me physically and mentally.

She is not sure when her next marathon will be but its unlikely to be this year now. Ill see how training goes, she says. At the start of the year I was going to do two marathons in 2023 but after London I thought it was a lot to do another marathon block during the second half of this year. I didnt think I was ready to do it again so soon.

Being injury-free is most important, especially with Olympic year coming up. My main targets for now are to target the half-marathon and 10km and run some PBs.

Based in Nottingham, she often trains at Loughborough University and is coached by former middle-distance international Vince Wilson. She also works one day a week as a dental nurse. It means I can switch off from training for one day a week and mix with different types of people who arent always athletes and I think it helps me, she explains.

After Riga she races 13.1 miles in Valencia on October 22 where conditions are likely to be more suitable for fast times. Having such a good range of distances, what is her sweet spot or favourite distance?

Theyre all so different, she says. The 10km and marathon are such different events. Its nice to have that kind of range and I do like them all in their own way. The half-marathon Im still kind of sussing out and my favourite distances are probably 10km/half-marathon.

Being an adidas-sponsored athlete she is also excited to try out the new Adizero Adios Pro Evo 1 that helped Tigst Assefa set a world record of 2:11:53 in Berlin. Charlie Purdue, who ran 2:22:17 to go No.2 on the UK all-time rankings in Berlin, is also an adidas athlete but wore the Adizero Adios Pro 3 model last weekend.

On the world record, Harrison says: What can you say? Its crazy. The times are getting faster and it makes you want to train that little bit harder to be near the top.

She adds: Charlie did fantastic and I dropped her a message to say well done. It was a phenomenal run to get a PB and become the second fastest ever Brit. Its certainly inspired and motivates me.

For the marathon Im still learning and hopefully in my next marathon Ill be able to use the lessons I learned from London and will hopefully run another good PB.
