The 2nd Road to Le Mans was an automobile endurance event composed of two 55-minute races contested by 49 teams of two drivers each racing Le Mans Prototype 3 (LMP3) and Group GT3 (GT3) cars. It took place on 15 and 17 June 2017 at the Circuit de la Sarthe, near Le Mans, France, as a support event for the 2017 24 Hours of Le Mans and the second round of the 2017 Le Mans Cup. The Automobile Club de l'Ouest (ACO) organised the second Road to Le Mans race in partnership with the FIA World Endurance Championship and the European Le Mans Series promoter Le Mans Endurance Management.

A Ligier JS P3-Nissan shared by John Falb and Sean Rayhall of United Autosports won the first race starting from sixth position. The M.Racing - YMR duo of Alexandre Cougnaud and Romano Ricci finished in second and RLR Msport's Alex Kapadia and Martin Rich were third. The GT3 category was won by the TF Sport pair of Ahmad Al Harthy and Tom Jackson driving an Aston Martin V12 Vantage GT3 after the Spirit of Race Ferrari 458 Italia GT3 of Maurizio Mediani and Christoph Ulrich was penalised for being deemed to have too short of a pit stop. The second race was won by the DKR Engineering team of Jean Glorieux and Alexander Toril over Falb and Rayhall. The M.Racing - YMR team of Erwin Creed and Yann Ehrlacher completed the overall podium in third. Al Harthy and Jackson completed a victory sweep in GT3 after the IMSA Performance team of Thierry Cornac and Raymond Narac was penalised for breaching the minimum pit stop time.

Background The Automobile Club de l'Ouest (ACO) formally announced the running of the 2017 Road to Le Mans race for Le Mans Prototype 3 (LMP3) and Group GT3 (GT3) cars that were not allowed in the 24 Hours of Le Mans in February 2017. The ACO along with FIA World Endurance Championship and the Le Mans Endurance Management, the promoter of the Le Mans Cup, organised the event. It was held on 15 and 17 June 2017 at the Circuit de la Sarthe, near Le Mans, France. This was the second running of the event, the second round of the 2017 Le Mans Cup and served as a support race for the 2017 24 Hours of Le Mans.

Colin Noble and Anthony Wells led the LMP3 Drivers' Championship with 25 championship points after winning the season-opening round at Monza. They were seven championship points in front of the second-placed Jean Glorieux and Alexander Toril and ten ahead of the third-placed Maurizio Mediani and Claudio Sdanewitsch. Phil Keen and Lee Mowle led the GT3 Drivers' Championship with 25 championship points after winning their class at Monza, seven ahead of Flick Haigh and Joe Osborne in second and ten ahead of Fabio Babini and Emanuele Busnelli in third. The 79 Nielsen Racing team led the LMP3 Teams' Championship with 25 championship points, leading the No. 3 DKR Engineering squad by six championship points and the No. 55 Spirit of Race by ten championship points. With 25 championship points, Lee Mowle's No. 7 squad led the GT3 Teams' Championship by seven championship points over the No. 75 Optimum Racing and nine championship points ahead of the No. 46 Ebimotors.

Regulations and entrants Entry to the race was open from 10 March to 6 April 2017. A total of 46 cars were permitted to enter the race, an increase of four from the 2016 event. The ACO's selection committee had the discretion to prioritise invitations to the LMP3 and GT3 categories from the ACO's continental racing series, the European Le Mans Series (ELMS) and the Asian Le Mans Series (ALMS), as well as the Asian Le Mans Sprint Cup and the IMSA SportsCar Championship. All current Le Mans Cup entries were automatically accepted. Each team was required to sign at least one bronze-rated driver (that is a gentleman driver) and their second driver could hold either a silver or gold-rated licence. Platinum-rated drivers (that is a professional driver) were barred from participating. A driver was permitted no more than 20 minutes to drive on the track. According to the race's regulations, all teams had to make a mandatory pit stop lasting no less than two minutes between the 22nd and 32nd minutes of both races. All competitors in the two categories were eligible to score championship points provided they finished anywhere from first and below. The two pole position winners in each class received one championship point.

The entry list was published by the ACO on 10 May 2017. The 49-car entry list included 33 LMP3 and 16 GT3 vehicles, an increase of 12 on the previous year's race. In addition to the 21 guaranteed Le Mans Cup entries, there were 12 ELMS entries, two from the ALMS while the rest of the field was filled with one-off entries only competing at Le Mans. Many of the LMP3 entries came from the Le Mans Cup and all but five fielded Ligier JS P3-Nissans. The five non-Ligiers were three Norma M30s and one Ginetta-Juno P3-15 and ADESS-03 each. There were seven manufacturers (Aston Martin, Audi, Ferrari, Lamborghini, McLaren, Mercedes-Benz and Porsche) who were represented in the GT3 category. Ben Barker, Richard Bradley, Christian Philippon, Michele Rugolo, and James Winslow were the five drivers and Graff, Gulf Racing UK, Larbre Compétition, Spirit of Race and United Autosports were the five teams competing in both the Road to Le Mans and the 24 Hours of Le Mans.
