The Heart of Racing Gears Up for the Twelve Hours of Sebring

Sebring, Fla. (March 11, 2025) – The Heart of Racing (THOR) embarks on a new chapter of the team’s IMSA WeatherTech SportsCar Championship history this weekend as the team prepares to make its first start in IMSA’s GTP category in the Mobil 1 Twelve Hours of Sebring on March 15th.

Sebring International Raceway will host the Aston Martin THOR Team Aston Martin Valkyrie’s American debut in the IMSA GTP class. Piloting the new No. 23 Heart of Racing Aston Martin Valkyrie will be long-time Heart of Racing drivers Ross Gunn, Roman De Angelis, and Alex Riberas.

The Heart of Racing has a long history with the No. 23 as it was the number the team first competed with when making its IMSA debut in 2020. That year De Angelis raced alongside Ian James and Darren Turner finishing second in the Twelve Hours of Sebring after starting from eleventh in the GTD category. During the 2021 edition of the race De Angelis and James were joined by Gunn to finish third.

The Gunn, De Angelis, and Riberas lineup holds five Twelve Hour of Sebring podium finishes with Riberas having won the race in 2015. In an IMSA sanctioned test at Sebring International Raceway in February De Angelis and Riberas completed 170 laps over five sessions with the Aston Martin Valkyrie. The trio is coming off of a successful Aston Martin Valkyrie international debut at the World Endurance Championship’s season opener in Qatar.

The Heart of Racing Team’s No. 27 Aston Martin Vantage entry will have Casper Stevenson, Tom Gamble and Zacharie Robichon behind the wheel in the GTD class. 2025 marks the fourth start at Sebring International Raceway for the No. 27 Heart of Racing Aston Martin with its best finish of fourth in 2024 with Robichon, De Angelis, and James.

Stevenson will make his second IMSA WeatherTech SportsCar Championship start in Sebring. The young driver competed at the Florida track in 2023 with the World Endurance Championship where Stevenson finished tenth. Stevenson was able to get a refresher on the bumpy course during the February test, having the fifth fastest lap time in session two.

Gamble and Robichon are also both coming off the Qatar race weekend, where Robichon finished sixth with James and Mattia Drudi in the No. 27 Heart of Racing LMGT3 entry. Gamble will make his second start at Sebring International Raceway after competing with the Heart of Racing in 2022. Robichon is no stranger to Sebring, having won his debut race at the track in the IMSA Porsche GT3 Cup Challenge USA in 2018. More recently, Robichon won the Twelve Hours of Sebring in 2021.

The Mobil 1 Twelve Hours of Sebring will have qualifying on Friday March 14th at 11:25am ET on the Peacock app. Saturday morning at 10:00am ET the Peacock app will have flag to flag coverage of the twelve hour enduro with additional updates on the Heart of Racing social media platforms.
