My two cycling-crazed roommates and I have developed several really cool, totally free, cycling-specific tools in our spare time, which we host on a server in our basement.
The first is https://sherpa-map.com this site uses the same backend software that RideWithGPS uses, but supports 28 routing profiles, auto route generation, the ability to project gravel roads, live weather radar, forecasted weather data along your route, project amenities such as gas stations, and so much more.
I even built in the capability for the routing service to pull satellite images in real time of roads with unknown surface type and use an AI I trained to classify the unknown road surface! Here’s a gif of that in action: https://i.imgur.com/ycs7pEe.mp4
Onto the next tool, https://sherpa-map.com/cycling-route-calculator.html this is a full-blown physics simulator for each point along an entire course (interpolating to 25 meter resolution) taking into account your bike setup, handling, power, etc. the idea is, given a course that’s say 20% mountain biking and 80% pavement it can model which setup will probably be fastest. It can also take into account weather data, modeling your power and aerodynamics against headwind, accounting for humidity, elevation, etc.
With this modeling and the forecasting, it’s probably the best tool to figure out what the raceday weather is going to look like because it can accurately predict where you’ll be when, it will even supply headwind/tailwind/ and all sorts of other data.
I’ve also recently upgraded this tool to support nutrition data, accounting for the intensity of your projected effort and breaking down the macronutrients/fluid loss/sodium loss/ etc. with gel/carb drink mix recommendations.
The last tool is https://sherpa-map.com/activity-racer.html
It lets you upload GPX Activity files of your past rides on the same course, or your buddy’s rides (if you want to grab their ride GPX file you’d need to use an extension like this)
Then, you can pit them against each other at any point in the course, press play, and watch them go! It’s similar to Strava’s Flyby feature, but gives you more data and puts you 100% in control, so you can even watch, as mentioned, previous versions of yourself vs yourself on the same course!
I thought I’d share these tools with you guys and gals, as fellow cyclists perhaps it will help be a free alternative to make a route, a good tool to find the race day weather across the course/choose the right setup/pick the right nutrition, and a fun way to visualize yourself vs your past self or vs your friends at various areas throughout the course.
If you have any thoughts or feedback on any one of these, please don’t hesitate to let me know!
