There are a growing number of people involved in Sportif cycle riding. This is a non-racing, yet competitive form of amateur riding. It is ridden in a team, each rider taking it in turns to block the wind at the front of the group, saving team mates up to 30% of their energy. This is achieved by performing a "roll", having the group rotate the front rider in a circular motion. In addition, many amateur cyclists use this rolling paradigm when riding together in social groups for fitness purposes.Unlike professionals, amateurs do not have team cars, management, and ear pieces, to tell them how to best manage this process. This disclosure proposes a method wherein a group of cyclists working together can have their drafting strategy managed by a cloud service that consumes data from their fitness devices and phones. Each rider carries a heart monitor and a mobile device that communicates to the cloud service. The service monitors each cyclists stress level, and knows the position of each rider in the group through techniques using Bluetooth Low Energy to calculate relative positions. With this information, the service is able to communicate to each rider their optimal riding strategy. Instructions sent to riders from the service may include telling a rider how long to stay at the front, giving them a countdown display, advising riders that are in trouble to stay at the back of the group, and managing the transitions between riders to distribute the stress in a way that optimizes the groups efficiency.

There are a growing number of people involved in Sportif cycle riding. This is the non-racing, yet still competitive, form of amateur riding. For example in Western Australia we have the Cyclosportif series (https://www.bwa.org.au/events/10/). This involves a team ride in a team time trial format with up to 9 team members. Generally you will have a team captain who makes the decisions on the road to speed up or slow down based on the information given to him by his team mates. This is similar to the team time trials in professional races. The concept is the same as with the professional races. You ride as a team, taking it in turns to block the wind at the front of the group, as this can save your team mates up to 30% of their energy. This is achieved by performing a "roll" or "roll through". The concept of a roll through is to have the group ride in a circular motion, riding forward up one side of a line of riders, briefly taking the wind at the front, before dropping backwards down the other side of the line. This keeps the group moving forward, sharing the effort of taking the wind. However, what differs with amateurs over professionals is we don't have a team car, a team director and ear pieces telling us what to do. In the professional ranks the team director can see when a rider is weakening by visual identification or monitoring of telemetry data such as heart rate and power output. For the growing number of amateur riders this data is now available on their fitness device, such as a Garmin, but no solution exists to manage this data from a team perspective. Often it is too late in a team event that a team mate tells you they are exhausted, pride being the normal cause. At this point they blow up and drop off the back, totally unable to keep up. If the group had noticed this and just decreased the speed by one or two kilometers per hour, then that team mate could still have performed a vital role to the team. If you lose more than one or two team mates, it does not matter how strong the other riders are, they will be weakened even more by taking turns on the front more frequently, to the point they will lose more time than if they had just reduced the speed by a couple of kph, and stayed with 8 or 9 riders.

In addition to racing itself, many amateur cyclists, the ranks of which continue to swell, use this rolling paradigm when riding together in more social groups for fitness.

Novelty statement: This novelty of this system is that it detects the order in which riders in a group/peleton are configured and then notifies the lead rider of how long to stay at the front before rotating to the back , based on real time heart rate data from each rider.

   The system does the following: • Using known techniques, knows the relative position of each rider in a group of cyclists , e.g. Alice is at the front, Bob is second, Carol is third and Danny is last
• From a heart rate monitor carried by each rider in the group, and...
