Decathlon is offering delivery within two hours in some Spanish cities.
The test will allow customers to place orders of products in store and receive them at their home in the time frame.
The service is now available in Valencia, Vigo and Tenerife and will roll out in Madrid and Barcelona soon.
The announcement came as Decathlon announced its financial results, with a 3% decline in turnover in 2018 to reach €1.9 billion.
The company plans to invest €41 million in 2019 to improve its omnichannel offering.
Recent projects include the introduction of a new logistics centre in León in the second quarter of this year. The company has also rolled out RFID technology across its stores, providing greater stock reliability.
"At Decathlon we are obsessed with offering our customers the best and most complete omnichannel service, adapting, and even anticipating their needs,” said Javier López, general director of Decathlon Spain.
