The fourth *base vita* of the Tor is in Gressoney. Runners have covered there 53 km with 4107 D+ since leaving Donnas. And we have intermediate times in Sassa and Niel.

Let’s see what we can learn from this first stage. What are the fastest times this far?

## Fastest Times

Fastest times in Sassa:

Karrera Iker 27:24 (2013)

Trivel Lionel 28:34 (2013)

Colle Franco 28:41 (2013)

Fastest times in Niel:

Karrera Iker 33:59 (2013)

Colle Franco 35:24 (2013)

Trivel Lionel 35:34 (2013)

Fastest times in Gressoney:

Karrera Iker 37:57 (2013)

Colle Franco 38:38 (2013)

Trivel Lionel 39:48 (2013)

Fastest times between Donnas and Gressoney:

[

~~Fornero Andrea 7:26 (2012)~~]

Perez Oscar 12:47 (2012)

Hamelinck Wouter 12:55 (2010)

Grange Giuseppe 12:59 (2010)

Colle Franco 13:07 (2013)

Again a probably wrong entry of a DNF that gives an impossible fast time. We see that some of the long sleepers in Donnas run as fast as the front runners.

Fastest times between Donnas and Sassa:

Favre Corinne 2:45 (2010)

Zanchi Marco 2:49 (2013)

Canepa Francesca 2:50 (2013)

Well, that are some surprising names.

Fastest times between Sassa and Niel:

[

~~Pidello Gian Marco 3:56 (2013)~~]

Karrera Iker 6:35 (2013)

Colle Franco 6:43 (2013)

Perez Oscar 6:59 (2012)

Fastest times between Niel and Gressoney:

[

~~Parisio Patrizio 1:40 2013~~]

Perez Oscar 2:45 (2012)

Calvo Redondo Salvador 2:48 (2013)

[Vuillen Loris 2:52 (2010)]

Grange Giuseppe 2:53 (2010)

Hamelinck Wouter 2:55 (2010)

## Sassa

The ones that pass Sassa in less than 60 hours have a very good chance of finishing.

Some variation in the location of the bulk. It might depend on how long people tend to stay in Donnas.

## Niel

We start to see that 72 hours in Niel is more or less the difference between finishing on Friday or finishing on Saturday.

No fixed time limit, but if you pass in less than 80 hours you are golden.

## Gressoney

75-76 hours is more or less the distinction between finishes on Friday and finishes on Saturday.

The time limit to get here is 85 hours. It looks like it is not strictly enforced (or was different in the past) and people do manage to get to the finish line past this time. As long as you are under the time limit you can do it from here on.

## Predictions

Some plots to help you predict how long it will take to get to the next aid station with timing.

I am sure that you can deduce a reasonable estimate from that.

## Time in Gressoney

To finish the discussion of leg 1, some more records. This time of the people that stayed in Gressoney for the longest time and still finished.

Hamelinck Wouter 10:34 (2010)

Pujol Herve 10:28 (2012)

Brunod Michel 10:02 (2012)

There are some good attempt, but nobody managed to break my time from 2010.

And to finish a plot to predict how long a runner will stay in the *base vita* depending on the time he arrived.

The line you see to the right are runners that stay until the time limit pushes them on.
