Echevarria, who long-jumped a legal 8.68 metres last season, as well as an electrifying 8.83m effort that was ruled out for record purposes for just a breath of extra wind, had to settle for second place on countback on his 2019 debut at the last Tour event in Karlsruhe on Saturday, having managed 8.08m.

But it was six months since he had last competed, and he is in confident mode for tomorrow’s competition, which will take place in front of a sell-out crowd of 5,200 in the Torun Arena. 

"It was a long time between competitions, so I was having problems finding my rhythm, especially on my approach," he said as he looked ahead to a return match with the Karlsruhe winner, Sweden’s Thobias Nilsson Montler.

"Tomorrow will be better."

Swoboda, winner of the European 60 metres indoor silver two years ago in Belgrade, won her heat in Karlsruhe in 7.08sec, 0.01 shy of the Polish record she set in 2016, before winning the final in 7.10.

She warmed up for Torun with a 7.13 win at the Orlen Cup in Lodz last night.

But the young Pole has serious opposition in Torun in the form of the Ivory Coast’s world 100 and 200m silver medallist, 30-year-old Marie Josee Ta Lou, the silver medallist in last year’s IAAF World Indoor Championships in Birmingham in a lifetime best of 7.05.

Meanwhile, the men's 400m pits America's Nathan Strother, winner in the World Series opening leg in Boston, against Karlsruhe winner Pavel Maslak.

The Czech runner, three times a world indoor champion, clocked 46.78, with Strother having recorded 46.97 in Boston.

The women's 800m features Britain’s Laura Muir in her first appearance over the distance this season – she will be seeking some speed work as she prepares to defend both her 1500m and 3,000m European indoor titles in Glasgow next month.

The presence in the field of Switzerland’s double European indoor 800m champion Selina Buchel should ensure she is sufficiently stretched.

The local favourite in the men's 1500m will be Marcin Lewandowski, whose most recent international accolade was silver over the distance at last year's World Indoor Championships.

 He finished behind 19-year-old Samuel Tefera in a tactical Birmingham final; the pair will be reunited in their 2019 debuts.

The IAAF World Indoor Tour is a series comprising of six meetings across the globe in which athletes compete for points in designated tour disciplines.

It includes further stops in Madrid on February 8 and Birmingham on February 16 before the finale in Düsseldorf on February 20, when the series winners will be crowned.

The winners will also be awarded $20,000 (£15,300/€17,500) prize bonuses and handed the first wildcard entries for the 2020 IAAF World Indoor Championships in Nanjing.
