Portuguese GP: When to watch every Portimao session and race live on Sky Sports F1

Lewis Hamilton and Max Verstappen are set to renew their on-track rivalry at this weekend's Portuguese GP - and you can watch all the Portimao action live only on Sky Sports F1.

The key times are:

• The race starts at 3pm on Sunday with build-up from 1.30pm

F1 re-enters the Portimao rollercoaster

F1 is back in Portugal and the Algarve International Circuit - colloquially known as Portimao, the nearby port city - for the second time in the space of half a year after a successful, and popular, debut for the venue last autumn.

• Hamilton, Russell, Norris to join social media boycott

The country had not staged a Grand Prix since 1996 but Portimao jumped at the chance to fill one of the spaces on the heavily-revised 2020 calendar, with the circuit having long targeted an F1 race.

Likened to a 'rollercoaster' owing to its undulation and twists and turns, the 2.9-mile lap quickly proved tricky for drivers to master.

An additional challenge at last year's race was a newly re-laid track surface, which initially offered little grip and triggered numerous mistakes from drivers through practice.

Light rain showers at the start of the race then exacerbated the search for grip and ended up producing one of 2020's most extraordinary opening laps, as then-McLaren driver Carlos Sainz surged from seventh on the grid to second place. He took the lead a lap later but Sainz was soon shuffled back as Mercedes' Valtteri Bottas and, ultimately, Hamilton took control of proceedings.

Hamilton won the race to break the record for the most wins in F1.
