They set off three days ago from Cherbourg, Normandy, in a party of 14 cyclists raising money for Welsh children’s hospice Ty Hafan.
They plan to arrive on the Cote d’Azur on June 9 after 800 miles on the road.
Event organiser Peter Bowen, a section leader at Tata Steel’s hot mill slab yard in Port Talbot, said: “We did John O’Groats to Land’s End two years ago but the weather was a washout, so this time we decided on France.”
Steven Hughes, another Tata section manager, said: “We hope to raise £5,000 and got off to a good start with £250 from Neath Round Table and with a support van for the trip from Port Talbot transport firm Runtech.”
David Martin, a team leader at Tata’s cold mill, is driving the support van and ensuring water and food is in good supply.
His 13-year-old son Jack is the youngest member of the French adventure.
Tata Steel Hub director Jon Ferriman said: “This is another example of our employees going the extra mile for good causes.”
