This MCP server provides specialized tools for cyclists to quantify their performance. Use calculate_ftp_20min to estimate your Functional Threshold Power (FTP) based on a 20-minute maximal effort, or calculate_ftp_ramp if you have completed a ramp test. The server also includes calculate_session_stress to determine the Intensity Factor (IF) and Training Stress Score (T/SS) for any training session using your established FTP and normalized power.

I just finished a 20-minute test with an average power of 300W and I weigh 75kg. What is my FTP and what are my power zones?

Your estimated FTP is 285 Watts (285 W/kg). Your power zones are: Zone 1: 0-156.75W, Zone 2: 159.75-213.75W, Zone 3: 217.5-256.5W, Zone 4: 261W-299.25W, Zone 5: 303W-342W, Zone 6: 346.5W-427.5W, and Zone 7: Above 427.5W.

My FTP is 250W. I did a 60-minute ride at 220W normalized power. What was my IF and TSS?

For that session, your Intensity Factor (IF) was 0.88 and your Training Stress Score (TSS) was 88.0.

Calculate my FTP from a ramp test where I reached exhaustion at 280W, weighing 70kg.

Your FTP is 280 Watts (4.0 W/kg). Your power zones are: Zone 1: 0-154W, Zone 2: 156.8-196W, Zone 3: 212.8-252W, Zone 4: 255.8-294W, Zone 5: 296.8-336W, Zone 6: 338.8-420W, and Zone 7: Above 420W.

Use the `calculate_ftp_20min` tool. Provide your average power during the effort and your body weight in kilograms.
