The event will provide an opportunity for participants to fine tune preparations for the London 2017 World Para Athletics Championships, which are due to take place from July 14 to 23.

Both the reigning Paralympic champion Peter Genyn and the former Paralympic champion Toni Piispanen line up in the men’s 100 metres T51 in what is expected to be a closely-fought encounter.

Belgium’s Genyn beat his Finnish rival to the line at the Rio 2016 Games, but Piispanen still holds the world record.

The pair could not be separated when they raced in the nearby town of Arbon recently, with both being awarded the same time.

Fresh from breaking the 200m and 400m T34 world records in Arbon less than a week ago, reigning world champion Walid Ktila of Tunisia will be hoping for a strong performance over 800m.

It is a distance in which the 31-year-old now looks particularly vulnerable, having lost out on Paralympic gold to the United Arab Emirates’ Mohamed Hammadi last year.

Hammadi beat Ktila over two laps in Arbon, smashing his rival’s world record in the process.

In the men’s 200m T42, Rio 2016 gold medallist Richard Whitehead of Great Britain is likely to battle it out for top honours with Frenchman Clavel Kayitare.

As for women’s competition, former Paralympic and world champion Terezinha Guilhermina of Brazil has made the trip over to Europe searching for a return to form this year after a disappointing display at Rio 2016.

With Paralympic champion Libby Clegg of Britain having ruled herself out of the World Championships due to injury, Guilhermina’s chances of success appear to have increased significantly.

She will be competing in the 100m T11 in Nottwil.

Home favourite Manuela Schär is among a stellar field in the women’s 1,500m T54, but the Swiss wheelchair racer will surely be buoyed by her recent successes, which include victory at both the Boston and London Marathons in April.

More recently she set a European record over 1,500m in Arbon.

Paralympic marathon champion Lihong Zou of China, Britain’s Jade Jones and Japan’s Kazumi Nakayama are all expected to put up a strong challenge.

In the women’s long jump T44, Paralympic silver medallist Stef Reid and Paralympic bronze medallist Marlene van Gansewinkel of The Netherlands are both likely to be in contention for gold.
