Video bonanza

I’ve just inherited an iphone 3gs with video recording capability. And I’ve been documenting some of the climbs around Birmingham, but up until this afternoon I hadn’t figured out how to do any of the fast descents with the camera because I needed to use both hands to brake. I realized if I mashed the iphone up against the handlebar, I could hold it in place with two fingers and still have a finger free to grab the front brake. Here is the resulting video of the S Cove Dr descent at 51.9mph … this is a bit on the slow side for the descent (typical max about 55-56mph, fast 58-60mph, fastest just over 60mph).

Here is a screenshot of the elevation profile with South Cove annotated. I took the video on the second time down the descent.

Earlier in this ride home from work, I took a video of the final part of the Vestavia Dr overlooking the Shades Creek valley with a view over to Red Mountain and downtown Birmingham. That video is included below:

This morning on my way into work, I took a video of the Dolly Ridge climb and Old Brook trail descent/climb. Below the video is an annotated elevation profile screenshot. The video starts shortly after the Skyland Dr roller coaster and runs until after the Old Brook trail descent and climb. Narration includes discussion of the April 2011 tornado which passed through Old Brook trail.

Long ride today working over the South Shades Crest ridge line

Fun ride today – much longer than I had planned – ended up being just under 102 miles with over 12,000 ft of climbing. I wanted to put in some hard efforts, so I put in a few KOM efforts. Ironically, the one I wanted most I completely missed (i.e., I rode up the wrong combination of roads). But I set two different KOMs on the combination of roads I did end up riding. Plus 5 others on the rest of the route. But perhaps what I was most pleased with on this ride was again inspired by cyclocross – riding up the Rocky Ridge woods trail which has a super steep trail with roots (but no rocks) at the beginning. I have cleared it once before on my road bike, but that was in the middle of winter when the trail was clearer than it is right now.

Also, I set a single second worth of power records on the ride – exactly 3’38” @ 433 watts – probably on the Altaloma – Renfroe KOM. See critical power curve below:
