What did we learn from the first day of the final F1 test? That there is hope for all of us when we get into out 30s. Felipe Massa is a machine!
Right, that's it from me for today. I'll be back again bright and early in the morning for day two. See you then!

That's a wrap.
Felipe Massa finishes the day with the fastest time after clocking 1:19.726 this morning.
Seconds before the chequered flag is waved there is a red flag.
Nico Hulkenberg has stopped on the track in the Renault...
Richard Stephenson: Williams car looks quick... shame they've got a journeyman and a rookie pedalling it.
Two minutes to go and Felipe Massa heads on out, possibly to try and clinch the most laps in a day crown. Sebastian Vettel has just surpassed his tally by completing lap number 164.
Jospehat Okora: @MercedesAMGF1, external may be struggling but no one can see that. I am impressed by @WilliamsRacing, external . Contender.
Felipe Massa pulls into the pits after completing lap number 163. An absolutely monumental effort and plenty of valuable data collected with that sort of mileage. I wonder how much Williams will be benefit from having his experience again this season?
A touch under 10 minutes to go, with Daniel Ricciardo, Sebastian Vettel and Stoffel Vandoorne among the handful of drivers pushing it until the final minute.
A marginal gain for Valtteri Bottas as he does a 1:20.924. He stays fifth, but moves to within half a second of Lewis Hamilton in P4.
Looks like Felipe Massa is going to finish top of the pile today. Fastest time and plenty of laps, an excellent day for the Williams driver.
Imagine if he won the title this year. Out of retirement to become world champion. Like something from a Rocky film.
Esteban Ocon has also been hard at it today. He's onto 123 laps and counting in the Force India. Impressive!
Ocon, one of the tallest current drivers, has had to pile on pounds in recent months to help cope with the physical demands the 2017 cars put up on the driver. He basically had to eat as much as he could. I can think of worse problems.
Lap number 150 for Felipe Massa. He's done more than the equivalent of two Spanish GPs in a day and will have some wobbly legs tonight.
As is often the case, I stick a times update and someone goes and puts in a lap to significantly alter it.
That someone just now is Nico Hulkenberg. He leaps up to P7 with a 1:21.589 on softs. That means McLaren have been the 10th quickest team today, with just Sauber below them.
Geoff Ford: Any chance we can get those time updates with the tyres too please?
As you said please, Geoff, I've chucked them in now.
Check the testing times update at 16:10 GMT, should pop in soon.
A bit of tinkering and a couple of tweaks later, Daniel Ricciardo heads out for some lappage with 40 minutes to go.
1) Felipe Massa - 138
2) Sebastian Vettel - 133
3) Esteban Ocon - 110
4) Kevin Magnussen - 72
5) Daniel Ricciardo - 67
6) Daniil Kvyat - 65
7) Valtteri Bottas - 58
8) Stoffel Vandoorne - 55
9) Lewis Hamilton - 49
10) Pascal Wehrlein - 47
11) Marcus Ericsson - 36
12) Nico Hulkenberg - 35
13) Jolyon Palmer - 15
