Fernando Alonso is back out on the circuit. Just to emphasise the improved reliability McLaren have shown in testing this year, he has just completed his 100th lap for the day.

BBC Radio 5 Live

Approaching the last hour of day three of testing. Can you believe that in two weeks time it will be new season eve? Two weeks!

To get you really in the mood for the coming season, Jennie Gow presents 5 live's preview show tonight on BBC Radio 5 live from 21:00 GMT.

Jennie has been scouring the paddock in Spain to get you all the latest news and interviews, so well worth a listen.

No update from Haas yet to shed any light on what happened to Romain Grosjean. 

A braking problem was behind his first off-track foray this morning but as to why he ended up in the gravel this aft? I'm none the wiser.

Fernando Alonso has been doing a race sim this afternoon, as Lewis Hamilton appears to have been but both have pitted so at the moment there's just Nico Hulkenberg, Felipe Massa, Max Verstappen and Felipe Nasr on the track.

Kimi Raikkonen surpasses 100 laps for the day and puts, that's his race simulation done and dusted. 

Whether it was truly good, bad or indifferent, I think he'll have just one word for how that went...

2. Felipe Massa 1:23.193 83 laps

3. Nico Hulkenberg 1:23.251 116 laps

4. Max Verstappen 1:23.382 113 laps

5. Nico Rosberg 1:24.126 81 laps

6. Felipe Nasr 1:24.760 97 laps

7. Fernando Alonso 1:24.870 95 laps

8. Pascal Wehrlein 1:25.101 34 laps

9. Daniil Kvyat 1:25.141 63 laps

10. Lewis Hamilton 1:26.488 33 laps  

11. Jolyon Palmer 1:27.182 47 laps

11. Romain Grosjean 1:27.196 66 laps

It has been a while since I mentioned Lewis Hamilton. He's just nudged up a couple of places to 10th after a 1:26.488 on medium tyres.

Those cards could not be much closer to his chest.

I wonder what Kimi's feelings are about this memorable day...

Good spot Zack. It appears his lap was indeed compromised by Daniil Kvyat in the third sector.

F1 journalist Dan Knutson in Barcelona: "Felipe Massa did a 1:23.344 on ultra softs compared to his fastest lap of 1:23.193 set on the soft Pirelli compound.

Force India are a bit of a puzzle at the moment. They looked really strong in the first week, but have been much less obviously competitive this week. Applying the same fuel- and tyre-correction calculations - admittedly flawed, even if they are the best we can do - put them second fastest last week but way down in the second half of the grid this week so far. 

However, Sergio Perez said after his running on Wednesday: “It was a good day, really promising. There is a lot of information around. I didn’t feel that comfortable with the car today, it was quite windy, especially in the afternoon.  But still a very good day with plenty of information and I’m quite optimistic.”

It has taken a while, but it looks like Jolyon Palmer is about to get back out in the Renault. 

Nico Hulkenberg has just made it 100 laps for the day in the Force India. Solid if unspectacular from them so far in testing.
