What do H, T, C and B mean in para-cycling?
B · Beginner · Classes and machines · 2 of 2Each division has its own classes, numbered from the most impaired. Handcyclists are H1 to H5, H1 being the most severely impaired. Tricyclists, who cannot balance a bicycle, are T1 and T2. Bicycle riders are C1 to C5, with C5 the least impaired. Vision-impaired riders on tandems form one class, B, whatever their level of vision.
How it works
- H1 to H5: handcycles; H1 most impaired.
- H1 to H4: recumbent riding.
- H5: kneeling or sitting position.
- T1 and T2: tricycles; T1 more impaired.
- C1 to C5: bicycles; C5 least impaired.
- B: tandems, one class.
- Code: gender letter then class, such as WC4.
- Changes: 2026 amendments revised H3 and H4.

Tricky cases
What does MH2 mean?
A man in handcycle class H2.
Are B1, B2 and B3 separate classes?
No. They race together as B.
Can a C2 rider use a fixed crank?
Yes.
What is the leg length rule for C classes?
A difference of at least 7 cm is eligible.
Why the rule exists
Classes keep riders with a similar level of function racing each other. One B class works because the pilot does the seeing.
