The first of four identical 1K-ish loops on rolling, curvy, forested trail. I was testing a few things:
(i) A new Ambit. For long ultras with drop bags in the middle, I switch Ambits at the halfway point to allow me to use a more accurate recording interval without worrying about battery life. My old Ambit2 is in the Suunto Hospital and may not survive so we found a cheapo replacement Ambit2 on eBay. (The cool kids buy Ambit3.)
(ii) On each watch, I'd set up a custom "20 Hr Ultra" mode so I wanted to be sure it was working properly and the same way on both watches. I've set up a 10-second GPS recording interval for this mode, as opposed to the 1-second interval I normally use for Running mode.
(iii) While I was at it, I've been wavering on whether to use Speedcross or Speedcross Pro so I switched shoes after each lap.
Loop #1 - Old Ambit, Running Mode, Speedcross
Running (Trail) 6:26 [3] 1.02 km (6:18 / km) +17m 5:49 / km
shoes: Salomon Speedcross Pro - Blue
Loop #2 - New Ambit, Running Mode, Speedcross Pro
Running (Trail) 6:24 [3] 1.03 km (6:14 / km) +19m 5:42 / km
shoes: Salomon Speedcross Bordeaux
Loop #3 - Old Ambit, 20 Hr Ultra Mode, Speedcross
Running (Trail) 6:23 [3] 1.02 km (6:14 / km) +22m 5:37 / km
shoes: Salomon Speedcross Pro - Blue
Loop #4 - New Ambit, 20 Hr Ultra Mode, Speedcross Pro
Shoe decision made: I'm going with the Speedcross. Big surprise - I always use them for ultras! If it ain't broke...
It looks like both Ambits are working fine and returning similar data. The 10-second GPS interval never seems much different compared to a 1-second GPS interval, even on curvy forest trails. Nice.
I'm still doing last-minute stuff but Timato, Mrs. Tiny and Aubrey are in the air on their way to Venice tonight. Yay!!
