Due to a distinct lack of cycling guests, I decided to use yesterday for some more research and practice for my calorie neutral bike ride world record attempt on 11th September. I thought I would test out the route for the potential last 8 cafes on my route.
For those unfamiliar with the calorie neutral bike ride concept then there are seven rules that must be followed for an official world record attempt. I have included the list of rules at the bottom of the post but for today I would be only focusing on rule 6.
Rule 6. From the time of arriving at the cafe 300 calories must be burnt off before the next cafe can be visited thus making the ride calorie neutral. (300 calories is based on in-depth internet research on average calories of cakes and scones plus average calories of a hot drink (Tea, coffee, hot chocolate).
Using the data from my previous two practice rides I had been able to optimised the route in order that the minimum distance would be needed between stops to be able to burn the necessary 300 calories. As always I was using my Garmin Forerunner 910XT, with a heart rate monitor, to measure the calories.
With GPS route, notebook and calorie counter all in place I set off early, before breakfast, to the start point for the day which would be the Hen House near Wymondham. On this ride I would only be stopping if I felt I was running out of energy as today it was all about the route.
With wind behind I was soon at the end of the drive to the Hen House so initialised my gadgets for a day of data gathering. I arrived at the first stop, which was Lincolns Tea Shoppe in Hingham, and I was confident that I had pedalled just the right number of miles in order to shift the necessary calories. On arrival I stopped and checked my Garmin Forerunner 910XT calorie count readout. I was shocked and mystified to find I had only burnt 223 calories. I was obviously disappointed and surprised that it was this many calories short but made a note to add a couple more miles on to the route and set off again.
Next cafe on the list was Tabnabs in Mattishall but checking my Garmin Forerunner 910XT calorie count on arrival I again found I was many calories short. If every cafe required an extra couple of miles then the 20 cafe target I had set for the world record attempt would not be possible. Rather dejected I decided to keep going and cycle to the next stop, Yaxham Mill Cafe Bar, to have Breakfast.

Suitably refuelled it was back on the bike for a loop round to Yaxham Waters cafe with the pattern of not enough calories repeated again.

When it arrived I was very pleased that the carrot cake was a very generous (and tasty) slice which, like a Pavlovian dog with an I-phone, I had photographed before I knew it.

I now felt fully recharged and so I hopped back on my bike for the ride to the last stop which was the Station Bistro in Wymondham with another insufficient calorie count.
When I got home I updated all the data to my spreadsheets which showed, according to my Garmin Forerunner 910XT, I was now operating at a much lower calories per mile rate than on the previous two practice rides.
With all the data I now had plus the inconstancies of my Garmin Forerunner 910XT calorie counting I was at a lose to know what to make of it all. I decided I needed to hand all the data over to some boffins so they could crunch the numbers in a super computer and come up with the answer as to how far I need to cycle between cafes in order to burn 300 calories and keep my ride calorie neutral.

I will therefore have to re do the route again on this basis and with no heart rate monitor to confuse things.
For clarity I have added a new rule, 8, about calorie counting equipment
Calorie neutral bike ride record attempt rules
1. The holder of the record will have visited the highest number of different cafes during a single day.
2. All cafes must be independent and not part of national chains
3. All cafes must be visited within their normal opening hours and not open early or kept opened late for a record attempt
4. At each cafe a standard portion of cake or a scone (fruit or cheese) must be consumed. Biscuits, flapjacks, tiffin or anything pre-packaged will not count.
5. At each cafe a standard hot drink must be consumed. (Tea, coffee or hot chocolate). If served in a pot or jug than one cups worth must be drunk.
6. From the time of arriving at the cafe 300 calories must be burnt off before the next cafe can be visited thus making the ride calorie neutral. (300 calories is based on in-depth internet research on average calories of cakes and scones plus average calories of a hot drink (Tea, coffee, hot chocolate).
7. If extra calories have been used up between cafes then that is tough as they can not be credited against other legs of the ride.
8. Calories burnt to be counted on a generic calorie counting device using only cycle speed, rider weight and age to calculate calorie usage. No heart rate consideration is required.
