One year ago, Echevarria begun what turned out to be a sensational season last year with victory in the German city, just four weeks before his surprise triumph at the 2018 IAAF World Indoor Championships in Birmingham. 

Still a teenager, he later went on to produce a superb outdoor campaign, topped off by an 8.68 metres personal best and a barely wind-assisted 8.83m leap at the IAAF Diamond League leg in Stockholm. 

His leap was just outside the allowable wind limit for record purposes, but it was still the longest in the world in 20 years. 

Tomorrow, Echevarria is set to face fellow 20-year-old Miltiádis Tentóglou of Greece. 

Tentóglou, the reigning European champion, started his season with success at the last month's Mediterranean Athletics Under-23 Indoor Championships in Miramas in France. 

He prevailed with a jump of 7.99m, marking an indoor career best. 

Hometown favourite Julian Howard, a four-time national champion in the event, is also in the long jump line-up at the Messehalle Karlsruhe.

Tour points will be on the line in seven other events, beginning with the women's pole vault which features the third meeting of the year between world and Olympic champion Katerina Stefanidi of Greece and rising American star Katie Nageotte.

Stefanidi prevailed on countback at the Pole Vault Summit in Reno in the US last month, when both athletes cleared 4.74m.

But Nageotte got the better of her rival in Boston last weekend, topping 4.86m on her opening attempt to claim the first IAAF World Indoor Tour win of her career. 

It was also an early-season world lead and Nageotte's second highest leap ever.

In the women's 60m, there will be a first head-to-head clash of 2019 between The Netherlands' Dafne Schippers, a two-time world 200m champion making her fifth appearance in Karlsruhe and aiming to replicate her victory from 2016, and Switzerland’s Mujinga Kambundji. 

The Dutchwoman is the fastest in the field, with a lifetime best of 7.00sec making her equal 10th quickest of all time.

Czech Republic's Pavel Maslák, meanwhile, heads the field in the 400m as he looks to repeat his win in Karlsruhe from 2012 - since when he has won three European indoor titles and three world indoor titles. 

A live stream of all the action will be shown on the IAAF's YouTube channel, part of the world governing body's ongoing efforts to bring its events to global audiences. 

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.

Now in its fourth season, this year’s series begun in Boston with the New Balance Indoor Grand Prix.

It includes further stops in Toruń on February 6, 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.
