The Tour de France began three gruelling weeks of sun, scenery and summits on Saturday, but what's the key to winning in this elite world of small margins? How about appetite for risk and the danger of crashing (of which there has been a lot in the first week)?

We're looking for feedback about ideas we have for Mathematrix events in 2025-26. Mathematrix is our student-led discussion group aimed at graduate and postdoc minorities in maths. We'd also love feedback and insight from allies and people at all career stages/roles within the Mathematical Institute. 

The form is multiple choice only/checkbox questions so it will be very quick to answer and is completely anonymous.

Crash in Le Tour
Cycling is a sport where victory often hinges on marginal gains. In elite races like the Tour de France, while power output and aerodynamics are well-known performance factors another crucial, but less visible, element is risk. A crash, even if minor, can end a rider’s race. Can mathematics help optimise racing strategies in a world where both energy and safety must be balanced?
