428w for 3.5 Mins Enough for a Strava Cycling Hill Climb PR?

Almost 1 mile climb that can be a sting in the tail on a long ride on Exmoor as it usually comes near the end of a ride for us Minehead riders and seems to take your legs away climbing up to Wheddon Cross from the South. The fastest times on the strava leaderboard come from a Local road race called the Stella Farrell a few years back so as at 97kg at the time of the ride I won't be worrying the top 10 even though this segment time was the fastest of the year... so far (August 2023). after dropping a bit of weight and completing some consistent cycling training I thought it was time to have a go at this Strava Segment to see if I could improve my time. #cycling #roadbike #stravacycling
