July 8^th, Day 20: Casper, WY to Lusk, WY: 106 miles, 2857 ft. ascent

Exciting news: We have updated our Route and Tracker page to include ride statistics from the Garmin GPS for the rides done so far.

From this we can calculate that our average speed over the whole ride so far (excluding parts where the Garmin malfunctioned) is a bit under 15 and a half miles per hour.

We've also started adding links to some great videos automatically generated from our GPS data by Relive, like this one of us crossing the Togwotee pass.

Today we were pleased to ride another 6 hour century on the first day of the third segment of our ride. However, we were even more pleased to receive an email from Nick East on the subject of Mairs-Heggie points, proving that at least some of our readers are as geeky as us. We reproduce this thoroughly excellent email below in its entirety:

RE: Mairs-Heggie Points

Hi Chris (and Alastair)

Hope it all continues to go well with tail winds and kind roads.  Congrats on exceeding the £100k fundraising point – really inspiring work!

I imagine you have thought of this, given you have plenty of time on the road for pointless naval gazing….

…but I found myself reading your ride descriptions thinking about other MH sequences that might give you some more daily milestones to aim for and check off with a celebratory banana. There are lots to choose from. Ratio of number of flies accidentally swallowed today to the ratio for the whole ride, volume in litres of Gatorade consumed.  Gun-racks spotted by overtaking pick-ups as proportion of the whole, etc. 

Of course, the most obvious is the vertical distance – easily found during the ride provided you have a cycling computer that shows you elevation gain. So I give you – Mairs-Heggie Peaks – the point on each day where you’ve climbed the same ratio of the day as of the whole ride.

For reference a table below with your MH points and peaks for each day and for extra geekiness a dual axis plot based on your blogged graph (distance miles on the left axis, elevation gain in feet on the right axis). 

Looks like you have a couple of back to back monster climbing days right at the end!  At least you’ll be altitude trained from the Rockies, and with titanium arses by then.   

Impossible to know without GPS analysis of the ride profile, tour-de-france style, but I wonder if there are any days when the MH Points and Peaks are reached simultaneously other than the obvious example of the last riding day?

Happy cycling.

Nick.
